However, to make a lexan RC car body truly stand out on the racetrack, it needs to be painted. Painting a lexan car body can be a fun and rewarding project that allows you to express your creativity and personalize your car. However, it can also be a challenging task that requires patience, attention to detail, and some experience with painting techniques. In this article, we will guide you through the process of painting a lexan RC car body, from preparation to final touches, and give you tips and advice to help you achieve a professional-looking result.

Preparing the Body

Before painting the lexan RC car body, it’s essential to prepare it properly. Follow these steps to ensure a clean and smooth surface for painting:

  • Wash the body with soap and water and dry it thoroughly with a clean cloth or paper towel.
  • Remove any stickers, decals, or glue residue from the body using a plastic scraper or rubbing alcohol. Be careful not to scratch the body.
  • Mask off any areas that you don’t want to paint, such as the windows or the bottom of the body, using masking tape or liquid mask.
  • Sand the surface of the body lightly with 400 to 600 grit sandpaper to create a surface that the paint can adhere to.

There are several materials and tools that you’ll need to prepare the body, including:

  • Soap and water
  • Plastic scraper or rubbing alcohol
  • Masking tape or liquid mask
  • 400 to 600 grit sandpaper
  • A clean cloth or paper towel

Some RC car hobbyists recommend using specialized cleaning products, such as Lexan cleaner, to ensure that the body is free of oils, dirt, and other contaminants that can affect the finish of the paint. Additionally, you might want to invest in a hobby knife or trimming scissors to help you cut masking tape and trim decals with precision.

What Paint for Lexan RC Car Bodies?

When it comes to painting Lexan RC car bodies, it’s important to use the right type of paint so that the paint adheres properly and doesn’t flake off. Here are some options:

  • Liquid paint: water-based, solvent-based, or lacquer-based paint formulated specifically for Lexan material
  • Aerosol paint: spay paint that is formulated for Lexan material
  • Dye: a specialized dye that permanently colors the plastic

Some popular brands that make RC car body paints include Pactra, Spaz Stix, and Duratrax. Whatever you choose, make sure to follow the manufacturer’s instructions carefully for the best results.

Choosing Paint for Your Lexan RC Car Body

Choosing the right type of paint for your lexan RC car body is crucial for achieving a flawless finish. Here are a few things to consider when selecting your paint:

  • Water-based or solvent-based: Water-based paints are easier to clean up and less toxic, but they may not adhere as well to the body. Solvent-based paints are more durable and have better adhesion, but they require more precautions during use.
  • Spray can or airbrush: Spray cans are easy to use and provide good coverage, but they can be messy and may not offer as much control as an airbrush. Airbrushing requires more skill and equipment, but it can produce a very smooth and even finish.
  • Color and opacity: Choose a paint color that complements your overall design and make sure that it has good opacity for even coverage.

When shopping for paints, keep in mind that certain brands and types are better suited for different types of bodies and applications. Some popular brands of paint for lexan RC car bodies include:

Brand Features Price range
Tamiya PS Great color selection, good coverage, dries quickly $7 – $10 per can
Spray Max 2K Durable, high-gloss finish, professional quality $20 – $30 per can
Spaz Stix Ultimate Mirror Chrome Realistic chrome finish, easy application $10 – $15 per can

Before purchasing, be sure to read reviews and do your research to find the best product for your needs and budget.

Applying Paint to Your Lexan RC Car Body

Once you’ve chosen the right paint, it’s time to apply it to your lexan RC car body. Here are some tips to help ensure a smooth and even application:

  • Start with a clean, dry body: Wash the body with soap and water and let it dry completely before painting.
  • Warm up the paint: Before spraying, place the can of paint in a bowl of warm water for a few minutes to thin it out and help it flow more smoothly.
  • Use light, even coats: Apply the paint in several thin layers, holding the can 6 – 8 inches away from the body and using a sweeping motion. Avoid spraying too much at once, as this can cause drips and runs. Wait a few minutes between coats to let the paint dry.
  • Work in a well-ventilated area: Paint fumes can be harmful, so make sure you’re working in a space with good ventilation or wear a respirator mask.
  • Protect the paint: Once you’ve applied your final coat, wait for it to dry completely before handling the body or adding decals. A clear coat can also help protect the paint and give it a glossy finish.
