Flex Paint for RC Car Bodies: A Comprehensive Guide
Introduction
Flex paint, also known as flexible paint, is a type of paint specially formulated for use on polycarbonate RC car bodies. It is designed to withstand the flex and impacts associated with RC racing without cracking, peeling, or chipping. In this guide, we will explore the benefits of flex paint, how to choose and apply it, and some advanced techniques for achieving professional-looking results.
Benefits of Flex Paint
Flexibility: Flex paint is highly flexible, allowing it to move with the polycarbonate body without cracking or peeling. This is crucial for RC racing, where bodies are subjected to constant bending and twisting forces.
Durability: Flex paint is extremely durable and can withstand the impacts and abrasions encountered in RC racing. It resists chipping and scratching, ensuring a long-lasting finish.
Adhesion: Flex paint adheres exceptionally well to polycarbonate, forming a strong bond that prevents peeling or flaking.
Water Resistance: Flex paint is water-resistant, protecting the body from moisture damage and the elements.
UV Protection: Some flex paints contain UV inhibitors that protect the body from fading and discoloration caused by sunlight.
Choosing Flex Paint
There are several factors to consider when choosing flex paint for your RC car body:
Brand: Several reputable brands offer flex paints specifically designed for RC car bodies, such as Tamiya, Pro-Line, and Createx.
Type: Flex paints come in two main types: solvent-based and water-based. Solvent-based paints provide better durability but require more care in application. Water-based paints are easier to use but may not be as durable.
Color: Flex paints are available in a wide range of colors to match your RC car’s design. Some brands also offer custom color matching services.
Applying Flex Paint
Preparation:
1. Clean the polycarbonate body thoroughly with soap and water or a mild cleaner.
2. If necessary, lightly sand the body with fine-grit sandpaper to remove any imperfections or residue.
3. Mask off any areas you do not want to paint.
Application:
1. For solvent-based paints, use a spray gun or brush and apply multiple thin coats, allowing each coat to dry completely. For water-based paints, you can use a brush or airbrush.
2. Hold the paint can or spray gun 6-8 inches from the body and apply even, sweeping strokes.
3. Allow each coat to dry completely before applying the next one. The drying time will vary depending on the paint and ambient conditions.
Finishing:
1. Once all coats are applied, allow the paint to cure completely for several hours or overnight.
2. Remove any masking tape and touch up any areas as needed.
3. For added protection and shine, apply a clear coat specifically designed for polycarbonate RC bodies.
Advanced Techniques
Multiple Colors: To create complex paint schemes with multiple colors, use masking techniques to separate the different color areas. Apply one color, allow it to dry completely, then mask off that area before applying the next color.
Decals: Decals can be applied to flex paint after it has cured. Use a setting solution to ensure the decals adhere properly.
Weathering Effects: To create realistic weathering effects, apply a sponge dipped in paint to the body and lightly dab on the surface. Use different shades of paint to simulate dirt, scratches, and other wear patterns.
Conclusion
Flex paint is a versatile and durable solution for painting RC car bodies. Its flexibility, durability, and adhesion properties make it ideal for the demanding conditions of RC racing. By following the tips and techniques outlined in this guide, you can achieve professional-looking results that will enhance the performance and aesthetics of your RC car.
