Detailing and Finishing

• Adding Features⁚ Attach details like headlights, taillights, and grills using appropriate adhesives or mounting methods.
• Sanding and Smoothing⁚ Once the adhesive has dried, sand the body again to remove any excess glue or imperfections. This will create a smooth and uniform surface.
• Priming⁚ Apply a primer to the body to create a smooth and uniform base for paint. This will also help the paint adhere better.

Mounting and Adjustments

• Chassis Mounting⁚ Secure the body to the chassis using body posts, clips, or other mounting systems. Ensure a secure and stable fit.
• Fine Tuning⁚ Adjust the body’s position and alignment to ensure proper clearance and a balanced look. You may need to trim or modify the body slightly to achieve the desired fit.
• Testing⁚ Once the body is mounted, test its performance on the track or trail. This will help you identify any issues with fit, clearance, or functionality.

Building a custom RC car body requires patience, attention to detail, and a willingness to experiment. Don’t be afraid to make adjustments along the way to achieve the desired look and functionality.

Painting and Detailing

The painting and detailing phase of your custom RC car body is where you can truly unleash your creativity. This is your chance to transform your blank canvas into a striking and unique masterpiece.
