RC Car Bodyshells: How to Choose, Paint, and Protect

Your RC car's bodyshell is more than just a pretty cover. It protects the chassis, electronics, and mechanicals from dirt, debris, and impacts. But with so many shapes, sizes, and materials available, choosing the right one can be overwhelming. In this guide, we'll walk you through the key factors to consider when selecting a bodyshell, how to paint it properly, and how to protect it so it stays looking sharp for seasons to come.

Whether you're replacing a cracked shell or upgrading to a new style, understanding the basics of bodyshell materials, fitment, and painting will save you time and money. Let's dive in.

How to Choose the Right RC Bodyshell

When choosing a replacement or upgrade bodyshell, the first thing to check is compatibility with your RC car's wheelbase, track width, and body mount positions. Most shells are designed for specific chassis types, so measure your car's dimensions and compare them to the shell's specs. For example, the RCG Racing MT-One Bodyshell - Pink is made for the MT-One platform, ensuring a perfect fit.

Material matters. Polycarbonate (Lexan) is the most common because it's lightweight, durable, and easy to paint. Some shells are made from ABS or other plastics, which are stiffer but less flexible. For bashers, a flexible shell can absorb impacts better. Also consider the thickness: thicker shells (e.g., 1.5mm) offer more protection but add weight.

Think about the style. Do you want a pickup truck, a buggy, or a touring car? The shape affects aerodynamics and handling. For off-road, a shell with higher clearance and sturdy mounting points is ideal. For on-road, a lower, sleeker profile reduces drag.

• Check wheelbase, track width, and body mount positions before buying.
• Polycarbonate is the go-to for its durability and paintability.
• Consider your driving style: bashers need thicker shells, racers prefer lighter ones.

How to Paint an RC Car Body

Painting a polycarbonate shell is done from the inside, which protects the paint from scratches. Start by cleaning the shell with warm soapy water and drying it thoroughly. Mask off any windows or areas you want to keep clear. Use a sharp hobby knife to cut the mask precisely.

Apply the paint in thin, even coats from about 15-20 cm away. Let each coat dry for 10-15 minutes before applying the next. For best results, use paints specifically designed for polycarbonate (e.g., Tamiya PS paints). They contain special additives that prevent flaking and adhere well to Lexan.

After the final coat, let the shell dry for at least 24 hours. Then peel off the protective film from the outside. If you want to add a backing color, apply a coat of white or silver after the main color to make it pop. Remember, the paint goes on the inside, so the outside remains smooth and glossy.

• Always paint from the inside for a durable finish.
• Use polycarbonate-specific paints to avoid cracking.
• Apply thin coats and let them dry fully between layers.

How to Protect and Maintain Your RC Bodyshell

To keep your bodyshell looking new, regular cleaning is essential. After a run, wipe off dirt and mud with a damp cloth. For stubborn grime, use a mild soap and water solution. Avoid harsh chemicals that can damage the paint or plastic.

Apply a protective coating like a clear polycarbonate spray or a specialized bodyshell protector. These add a sacrificial layer that can be peeled off when scratched, revealing a fresh surface underneath. Some racers use a film or tape on high-wear areas like the front bumper and sides.

Store your RC car with the shell off when not in use to prevent warping. Keep it out of direct sunlight to avoid fading. When transporting, use a padded bag or wrap the shell in a soft cloth to prevent scratches.

Inspect your shell regularly for cracks or stress marks. Small cracks can be repaired with shoe goo or a similar flexible adhesive, but if the shell is badly damaged, it's time for a replacement. For example, the RCG Racing Wind Speed/Storm Rider Front Bumper is a great accessory to protect the front of your shell from impacts.

• Clean your shell after every run to prevent dirt buildup.
• Use a protective film or spray to minimize scratches.
• Store the shell off the car and away from sunlight.

Choosing the right RC bodyshell, painting it with care, and protecting it with a few simple habits will keep your car looking great and performing well. Whether you're upgrading to a new style or replacing a worn-out shell, these tips will help you get the most out of your investment. Happy driving!
