Best Model Paint for Plastic

When it comes to building and painting plastic models, whether you’re constructing a scale model of a car, airplane, or military figure, the type of paint you use can make all the difference in achieving a professional finish. Plastic surfaces can be tricky to work with, as they require paints that bond well to the material, resist chipping, and provide a smooth, even finish. This guide will walk you through the best model paints for plastic, how to choose the right paint, and helpful tips for applying it.

Why Paint for Plastic Models is Different

Plastic models are typically made from polystyrene or other similar materials. This type of plastic can present challenges when it comes to painting, as it is non-porous and smooth. If you choose the wrong paint, it may peel, chip, or not adhere properly, resulting in a lackluster finish.

To achieve the best results, it’s important to use paint specifically designed for plastic surfaces. These paints are formulated to bond well to plastic, resist fading, and hold up against handling, all while offering the vivid colors and smooth finishes that model enthusiasts expect.

Types of Paints for Plastic Models

There are several types of paint you can use for plastic models, each with unique characteristics. Let’s break down the most popular options:

1. Acrylic Paints

Acrylic paints are a popular choice for plastic modelers because they are easy to use, fast-drying, and provide vibrant colors. They are water-based, which makes them easier to clean up than oil-based paints.

Pros:

• Quick Drying: Acrylics dry much faster than oil-based paints.
• Water-Based: Easy cleanup with water, no need for strong solvents.
• Low Odor: Acrylics have a much lower odor than many other types of paints.
• Variety of Finishes: Available in matte, gloss, and satin finishes.
• Non-Toxic: They are safer to use, making them ideal for indoor use.

Cons:

• Less Durability on Its Own: Acrylics may need a clear coat to protect the paint from scratches and chips.
• Can Require Multiple Coats: Acrylics can sometimes require more coats to achieve full coverage.

Best Acrylic Paints for Plastic Models:

• Tamiya Acrylic Paints: Known for smooth coverage and a wide range of colors.
• Vallejo Model Color: Offers excellent pigment quality and a vast color palette.
• Citadel Paints: Perfect for smaller models like miniatures, with a wide selection of colors and finishes.

2. Enamel Paints

Enamel paints are another popular option for plastic model kits. They have a smooth finish and provide durability, but they take longer to dry than acrylics. Enamel paints are also oil-based, making them more resistant to scratches and wear.

Pros:

• Durability: Enamel paints are known for their long-lasting, resistant finish.
• Smooth Finish: Provides a glossy finish that’s ideal for highly detailed models.
• Longer Working Time: Enamel paints allow you more time to manipulate the paint before it sets.

Cons:

• Longer Drying Time: Enamel paints can take anywhere from 24 to 48 hours to fully dry, making it less ideal for time-sensitive projects.
• Stronger Odor: Because they are oil-based, enamel paints emit a stronger odor, requiring good ventilation.
• Cleanup with Solvents: You need mineral spirits or enamel thinner to clean your brushes and tools.

Best Enamel Paints for Plastic Models:

• Testors Model Master Enamel Paints: Offers smooth application and a wide range of colors.
• Humbrol Enamel Paints: Known for their durable, glossy finish and excellent coverage.
• Vallejo Model Air: Specifically formulated for airbrushing, providing smooth coverage and vibrant color.

3. Lacquer Paints

Lacquer paints are some of the most durable paints available for plastic models. They dry quickly, resist scratching, and offer a hard, glossy finish. However, lacquers can be tricky to work with because they require proper ventilation and specific tools.

Pros:

• High Durability: Lacquer provides a tough, long-lasting finish that is resistant to chipping and scratches.
• Fast Drying Time: Lacquer dries incredibly fast, which can be a major advantage if you’re working on large projects.
• Smooth Finish: Creates a high-gloss, smooth finish that is ideal for scale modelers.

Cons:

• Strong Odor: Lacquer paints have a very strong smell and require good ventilation.
• Requires Proper Ventilation: You should always work with lacquers in a well-ventilated area, or use a respirator.
• Tough Cleanup: You’ll need lacquer thinner or a similar solvent to clean your brushes and equipment.

• Mr. Color Lacquer Paint: Famous for its wide range of colors and consistent quality.
• Tamiya Lacquer Paints: Offers a glossy finish and dries incredibly fast.
• Alclad II Lacquer: Best known for high-quality metallic finishes.

4. Spray Paints

Spray paints are a convenient option for covering larger areas of your model quickly. They provide even coverage without the need for brushes, making them a great option for base coats and for finishing large models.

Pros:

• Even Coverage: Spray paints provide an even layer of paint without streaks or brush marks.
• Speed: Spray paints allow for fast application, which is great for large models or base coats.
• Great for Airbrushing: Many modelers use spray paints through an airbrush for detailed work.

Cons:

• Requires Ventilation: Spray paints require adequate ventilation because of the fumes.
• Hard to Control for Small Areas: While great for large surfaces, spray paints can be challenging for intricate or smaller models.
• Can Overwhelm Fine Detail: Spray paints can obscure delicate details if applied too heavily.

Best Spray Paints for Plastic Models:

• Rust-Oleum Spray Paint: Widely available and offers a variety of colors and finishes.
• Tamiya Spray Paint: Known for its great adhesion and color fidelity.
• Krylon Spray Paint: Offers a range of model-friendly spray paints.

How to Paint Plastic Models: Step-by-Step Guide

Step 1: Preparation

Before applying any paint to your plastic model, proper preparation is key:

• Clean the Model: Use warm water and mild soap to clean your model and remove any dirt or oil.
• Sand the Surface: If your model has rough or uneven areas, lightly sand it to create a smooth surface for painting.
• Prime the Model: Applying a primer designed for plastic will help the paint adhere better and provide a more uniform finish. Use a plastic-specific primer for the best results.

Step 2: Choose Your Paint

Based on your preferences, choose an acrylic, enamel, or lacquer paint. Acrylics are the easiest to work with for beginners, while enamels and lacquers offer durability and a more professional finish.

Step 3: Apply the Paint

If using spray paint, ensure you apply several thin coats to avoid drips. For airbrushing or brush application, use smooth strokes to achieve an even layer.

Step 4: Let It Dry

Let the paint dry fully between coats to avoid smudging or streaking. Drying times will vary depending on the type of paint you use, but always allow sufficient drying time.

Step 5: Finishing Touches

Once the paint has dried, you can apply additional layers or weathering effects. For extra protection, you may want to apply a clear topcoat or varnish.
