Introduction

Model edifice is a fascinating hobby. However, the quality of the finished production will depend on your skill level and tools used. Listed below are levels indicating what finishing products and tools are required to assist you in achieving levels of expertise. Every bit with any new learning feel, in that location is an entry level on which skill is built. A word to the wise: remain positive, patient and persistent so that you achieve and bask the satisfaction of assembling and completing models to exist proud to display.

Entry Level (Occasional model builder) – Precision Cement, hobby knife, paint set, brushes.

Intermediate Level (Striving to heighten skills) – Precision cement, liquid cement, single action airbrush, propane, compressor (optional), tweezers, putty, sanding films, sprue cutter (optional), hobby knife, Model Primary brushes, airbrush thinner, castor cleaner/thinner.

Advanced Level (Has achieved excellence) – Professional double action airbrush and accessories, compressor with regulator & moisture trap, above mentioned supplies, Dullcote, Glosscote, Lacquer Thinner, Model Primary paints, Model Master brushes.

Enamels

To preserve your enamel paint and preclude the inner seal and cap from sticking to the bottle'southward rim, we recommend that you not paint direct from the bottle. Subsequently thoroughly stirring your paint, pour out merely the corporeality of paint you need for your project into another small container (orange juice hat, etc.), cap the canteen and paint from this container. Practice not pour separated paint back into canteen. By not painting directly from the bottle, evaporation is reduced and the likelihood of having to use a thinner is decreased. Depending on the amount of thinner used, the added solvent can slightly lighten the color of the enamel.

Information technology is important to achieve a make clean seal prior to storage of the enamel. Wipe away all excess paint from around the outside canteen cervix and inside the cap's rim. While storing the enamel, capsize the bottle to foreclose oxygen diffusion into the bottle causing the paint to solidify. When thinning enamels for airbrushing, utilise but our enamel airbrush thinner. Merely our enamel cleaner/thinner should be used for thinning bottled enamels. Both can be used for clean up.

To obtain the all-time finished picture consequence, aerosol paint should be applied in several fine mist applications building upwards coverage. This procedure will reduce drips, runs and sags. Wait v minutes betwixt coats. To achieve a gloss finish, your terminal coat should be practical heavier giving the cease a wet appearance. Do not apply paint between 3 to 48 hours of last awarding. Enamels are sensitive to environmental conditions. To learn more, refer to "Trouble Shooting" department.

Lacquers

Unremarkably lacquers should not be applied over enamels due to their incompatibility with one another. However, Testor hobby lacquers are generally compatible with our enamels and acrylics in their dry state. Exceptions are noted further on.

The 1400 series of Metalized Lacquers are offered in bottled airbrush ready buffing and not-buffing coatings. Due to demand, Aluminum Plate, Stainless Steel, Magnesium, Titanium and Gunmetal colors were added in aerosol form.

Coatings should be applied in multiple fine mist applications building up a compatible coverage. When using the buffing coatings, gently rub out the dried pic to achieve a gloss reflectance. When sealing the buffing colors, utilise Production Numbers 1409, 1459 or 1261. When necessary, test decals markings for compatibility prior to placement. Mist on applications of the sealer so as not to diminish the reflectance. A give-and-take of caution, utilise a water based acrylic equally the sealer over No. 1418 Aluminum.

Non-buffing coatings need to be sealed prior to the application of our enamels or acrylics. For make clean upwardly and over spray, utilise Product Numbers 1159 or 1419 Thinner. Use a wet mask or our no-tack masking material, Parafilm.

Glosscote and Dullcote lacquers are generally compatible with our acrylics and enamels. However, aerosol lacquer Product Numbers 1260 and 1261 should not be applied on metallic aerosol enamel Numbers 1244, 1246 and 1251. Use enamel articulate overcoats instead. When applying, be enlightened of your ecology conditions. As well much humidity will result in blushing or hazing. Refer to the "Trouble Shooting" section. Information technology is very important when using Dullcote that all the dulling agents are thoroughly mixed into the solvent prior to application. If not sufficiently mixed, the finish volition appear as a white blotchy, snowy blanket. When this occurs, the lacquer coating can exist hands removed without harming the decal markings or enamel blanket. Refer to the "Removal" section. No 1159 Lacquer Thinner should exist used when airbrushing the lacquers and for clean up.

To raise adhesion of our decal markings to not-painted models, we recommend that the surface first be sprayed downwards with Glosscote.

Troubleshooting

Modeling tin be fun and interesting, simply keep in mind that along with the skillful experiences, you will encounter problem areas. Approach these problems as positive learning experiences in developing your skill level. Some problems may evidence up because of how the paint was applied, when it was applied and where it was applied. Below are descriptions, causes and suggestions on how to avert unsightly paint finishes and add to the life of the product.

Thickened Paint

The most common crusade of thickened bottled paint is caused past the evaporation of the enamel solvents or h2o. The evaporation of the liquid is usually due to painting directly from the bottle and while the paint is in storage. When brush painting an extended fourth dimension, cascade out into a separate container the amount of pigment required. Wipe away backlog paint from effectually the bottle rim prior to cap placement. Capsize canteen during storage. These 2 suggestions will reduce the evaporation process increasing the paint's longevity. Paint volition also thicken or gel when the wrong thinner is used. A discussion of caution: not all thinners are created equal. Use the recommended thinner for the product for the best results. Paint will also thicken or jell up when an incompatible thinner is used. Left over paint thinned with airbrush thinner should not be poured dorsum into the original bottle.

Thin Paint

When experiencing watery, sparse, low coverage bottled paint, the nearly common gene associated with this is the insufficient mixing of the pigment and liquid. But shaking the bottles will not provide the correct viscosity of the paint to achieve coverage. A stir stick or brush handle should be inserted into the paint to stir the pigment into the solvent. This procedure should as well be followed when nuxing paints earlier pouring into a cup and thinned for airbrushing.

When low coverage is experienced using droplets paints, the two near common causes are that the substrate needs to be color neutralized or a transparent color is beingness used. All our Candy colors are transparent paints. If experiencing low coverage when airbrushing, ordinarily too much thinner has been added.

Orange Skin

Orange skin is like shooting fish in a barrel to spot. The terminate resembles the peel of an orangish. It is caused by the rapid evaporation of the solvents either while the pigment is drying, or when the paint is being applied. It becomes more pronounced at higher temperatures and/or when lower humidity weather condition be. Orange peel can likewise happen if the droplets paint can or airbrush is held also far away from the object existence painted nether atmospheric condition, when using too much thinner in an airbrush or allowing the model to dry in a spray booth with the exhaust fan on. Information technology is normally but visible on gloss finishes. Once orange peel develops, it is necessary to remove the film and beginning over. Orange skin can exist experienced when applying enamels, polyurethane's and vinyl acrylic lacquers.

Self-Lifting/Wrinkling

"Self-lifting," is a common occurrence associated with gloss finishes. The finish will resemble a spider web or a cracked mirror appearance. Self-lifting occurs when an application of pigment is practical between iii and 48 hours after the last awarding. To eliminate this problem, but utilise subsequent coats of enamel before iii hours or after 48 hours of the last awarding. Self-lifting can occur when applying enamels and polyurethane's.

Fisheye

"Fisheye" is the formation of depressions or craters on the flick with a black dot in the heart of the bubble. This reaction occurs when there is contamination of the pigment, with the equipment or in the environs. This can be extremely hard to isolate and eliminate the cause. Fisheye can occur on flat and gloss finishes with any production formula.

Bubbling

Bubbling is the formation of many small bubbling in dried enamel moving picture. This can cause a gloss end to have a dull, rough appearance. This reaction is not uncommon when applying gloss enamel solvent-based spray paints when humidity is excessively high. To reduce the risk of occurrence, spray only when relative humidity conditions are 60% or lower.

Hazing/Blushing

Hazing, associated with lacquers, appears equally a cloudiness in the dried clear or pigmented motion-picture show. This reaction is commonly found with lacquers when relative humidity conditions are high trapping moisture in the dried moving-picture show.

If hazing develops, mist on a compatible lacquer over the film once the humidity level has decreased. The thinner dissolves the top layer of the lacquer picture and allows the moisture to evaporate. The application of besides much thinner will upshot in ruining the end.

Runs, Sags, Drips

Runs, sags and drips are usually acquired by the application of as well much paint or the improper mixture of the paint. To avoid this, apply several light applications to build up coverage making certain that the bottled paint has been stirred or aerosol pigment has been thoroughly shaken. Also, when applying a transparent pigment, use gold, silver or copper primer as an nether coat. When a primer is not applied beginning, usually likewise much paint is applied in an attempt to achieve opaque coverage ultimately causing runs, sags and drips.

Film Drying

When paint is not drying on the surface, the about common cause is that the wrong pigment was practical. When painting flexible vinyl or rubber, our solvent based enamel will not dry. A h2o based acrylic paint should exist used. Dry out fourth dimension on acrylics is virtually 15 minutes mminutes and enamels are dry to the touch between thirty minutes to 1 hour. Lacquers dry fifty-fifty faster. However, the environment and thickness of coats will have an touch on the amount of time it takes for the films to thoroughly dry out.

Macerated Paint Adhesion

Information technology is important to wash your model with a mild dish washing detergent to remove mold release residue from the model. If any oily substance is on the model, the cease may appear blotchy and take diminished adhesion. Adhesion will also be compromised if acrylics are over thinned.

Melted/Etched Plastic

Polystyrene plastic will misconstrue and even cook if exposed to estrus, and information technology will develop an etched surface advent if certain solvents contact information technology. Cement should exist applied sparingly to avoid melting parts, macerated adhesion and the loss of the cement'due south bonding or welding characteristic. When removing paint from polystyrene, never saturate the surface with thinner. Refer to "Moving picture Removal".

Silvering

When stale decal markings on a model take a cloudy appearance, this is referred to as "silvering". Silvering occurs when decal markings are placed on a flat-coated surface and air is trapped betwixt the paint and decal marking. To eliminate this, markings must be practical to gloss coated surfaces. If pigmented flats have been used, utilise No. 1261 Glosscote lacquer prior to placement of the decals. For those challenging areas, use our No. 8809 Decal Application System. "

Once the new markings are properly applied, allow them to dry for 24 hours to shrink dorsum into their original shape and thoroughly dry out before lightly misting on several applications of the Dullcote or Glosscote. Wait about 5 minutes between coatings.

Incompatibilities

Adverse reactions are manifested by either environmental conditions or chemical incompatibilities between solvents and substrates. When mixing or applying products in their wet or dry state that are not recommended by the manufacturer, it is advantageous to test on the side for compatibility.

If experiencing enamel that isn't drying, the substrate is probably flexible vinyl or a combination of flexible vinyl/polystyrene. Solvent-based pigment will never dry on vinyl. At that place are no solvents or procedures that will force the enamel to dry. The only ways of reversing this adverse reaction is to remove the enamel picture and beginning over using water based acrylic.

It is of import when using any solvent overcoat on decal markings to examination for compatibility betwixt the chemical sealer on the decal canvass and the solvent overcoat. Fortunately, when applying our decals supplied in our models, there is compatibility, and testing is not required. However, always lightly mist on the lacquer spray so as not to saturate and destroy even our decal markings.

When there is an incompatibility, the decals will wrinkle or chimera up once the overcoat has been applied. Should this occur, remove the markings and utilise a water-based acrylic as the overcoat. E'er test competitor'due south decal sheets prior to the placement of the markings on the model.

Cements

Cements should be viewed as tools. No one cement is going to exist able to provide the all-time results. For instance, when cementing or bonding a long fuselage together that is slightly warped, you would crave cement that doesn't evaporate quickly. In this situation, you would not want to use a fast evaporating liquid cement. You lot would choose a slower drying cement that enabled you plenty time to employ and brace the parts together. For this reason, we offering a variety of cements.

A word of caution: with the exception of the Clear Parts Cement and Instant Plastic Adhesive, our cement can dissolve the polystyrene when also much is practical. This is manifested by the lack of parts adhering to one some other.

The reason why our polystyrene cements work and so well is that the cement becomes a part of the polystyrene model. The cement welds parts together when the correct corporeality is used. When besides much cement is practical to a office, it becomes soft and once the glue dries out, the plastic becomes brittle.

If using primarily our tube cement, we now have a needle nose applicator cement (No. 8872 or 3507), that has much more control of placement. It has the same swell formula. When using the tube cement, employ the cement with a toothpick.

Some hobbyists have a problem with our No. 3502 Liquid Cement in achieving adhesion. The cement should be practical by means of capillary activeness. Hold the parts together, apply the cement using a 0 size brush and allow the solvent to run along the seam area. The castor that you select for this awarding must exist designated for only the cement. To aid identify this brush from others and too reduce tipping over the cement canteen, pause the brush handle in half. If the handles are painted and the paint dissolves in the cement, the cement will not be compromised.

Film Removal

Pactra Acrylics – Isopropyl Rubbing Alcohol and fabric removing in layers Model Master Acrylics – 50/50 mixture of Isopropyl Rubbing Alcohol and No. 50498 Cleaner and soft cloth in layers Enamels – Spray down picture show with Like shooting fish in a barrel Off droplets oven cleaner, after 1/2 hr. rub motion picture under warm water. Repeat it necessary or remove in layers using enamel thinner. Using a paste auto wax, light rub in circular motion with soft material enamel from articulate parts. When removing metallic enamels, apply a lacquer thinner for best results. Dullcote/Glosscote – Isopropyl Rubbing Alcohol and soft cloth in layers. Frequently alter to clean areas on material or moving picture build upwards on cloth will but smear effectually the film and non remove the lacquer. RC Auto Racing Paints – Use a 50/fifty mixture of Isopropyl Rubbing Alcohol and RC thinner with a soft cloth in layers. Very easy to craze the polycarbonate surface if likewise much pressure or RC thinner is used.

Decal Placement

Later advisedly masking clear areas, spray entire model with Testor/Model Chief Clear Glosscote Lacquer (#1261, #1161 or #1961) Decals adhere best to a smooth surface and the shinier the finish the smoother information technology is. Allow the Gloss Clear Lacquer to dry completely earlier going farther. Select the decals you plan to use and cut them from the decal canvass with pair of scissors or a Testor Hobby Knife. Working with only one decal at a time, dip the decal in clear water for no more than than five seconds. Remove it from the water and place on a dry out paper towel for about ane minute. When the decal slides easily on the backing paper, slide it to the border of, and onto, the surface of the model with a soft Testor Model Chief paintbrush or tweezers. Retrieve the decals are very sparse and tin can be easily ripped. Work slowly and carefully. Once the decal is in the desired position apply a small corporeality of Testor Decal Set up #8804. This will help the decal suit to any irregularities in the surface of the model. Allow the decal to dry out undisturbed. Should you desire to purposely motility information technology before it has dried, apply a little Decal Ready to a soft castor and push the decal slowly to the desired position. When the decals are completely dry (usually 24 hours) apply a glaze of Testor Glosscote (# 1261) or Testor Dullcote ( 1260) to protect the surface of the model. Now you can advisedly remove the masking from the clear parts.

Decal Removal

The most effective manner to remove the markings is past the application of household vinegar or Micro Scale'due south Micro Sol. Allow the solvent or vinegar to soak through the decals to loosen upwards the adhesive (time gene could be five minutes to I hour). Periodically check the markings and when ready gently remove the decal the markings with tweezers.

Cement Removal

Any solvent that will remove the cement from a model volition too destroy the model. Refer to the "Cement" section. Even so, nail smoothen remover that contains acetone will remove the cement. Blot at affected area with a make clean material and so as not to smear.

Pactra RC Car Racing Finish Paints

RC colors are vinyl acrylic lacquers that are peculiarly formulated for flexibility on the underside of polycarbonate bodies. Overcoat the RC paints to fuel proof using Pactra'south No. 20087 Clear Varnish (high gloss). Since the Clear Varnish does have an amber tint to information technology, nosotros practise non recommend using the varnish over white. RC'due south are sensitive to hazing/blushing. Refer to the "Potential Problems" section. When airbrushing the pigment, a starting bespeak of 9 parts paint to 1 part RC thinner is recommended.

In society to avoid the RC paint from chipping or peeling, it is of import to remove all mold release residue from the surface prior to spraying or masking. Apply the paint in light applications. When the torso is held under direct calorie-free, you should be able to see through the paint. If also much pigment has been applied, not simply does this create runs, sags, drips and haemorrhage under the electrical masking tape, but it also enhances the likelihood that the paint will pull away from the polycarbonate.
