Frequently Asked Questions

For polycarbonate RC car bodies, it is recommended to use Lexan/polycarbonate compatible paint, which is specifically designed for the material. This ensures proper adhesion and reduces the risk of cracking or peeling.

Before painting a Lexan RC body, start by cleaning the body thoroughly to remove any dirt, dust, or debris that could affect the paint job. Use a combination of soap, water, and a soft brush or cloth. Mask off any areas that do not need to be painted, such as windows, trims, and mirrors, and be sure to remove any protective film on the body if present.

While it might be tempting to use regular spray paint on RC car bodies, it is not recommended. Polycarbonate bodies require Lexan-specific paint, whereas styrene or ABS plastic bodies can use standard enamel spray paint. Using the right paint ensures a proper finish and longevity.

Using a liquid mask is an effective method for masking intricate designs or details on an RC body. Apply the liquid mask in thin, even layers, allowing each layer to dry before applying the next. To create a custom design, draw the design onto the dried liquid mask with a fine-point marker or pencil, then carefully cut the design out using a sharp hobby knife. Be sure to cut through the mask without damaging the body itself.

Achieving a metallic finish involves using a combination of metallic spray paint and a clear coat. Start by applying a base coat of metallic spray paint, followed by a layer of clear coat to protect and enhance the metallic effect. Additional coats of clear can be applied to achieve the desired level of shine.

To create custom patterns and designs using paint stencils, first choose or create a stencil that suits the design desired. Cut any required shapes out of adhesive-backed stencil material or low-tack vinyl, then position and apply the stencil onto the prepared RC body. Make sure the stencil is smoothed down properly to prevent paint from seeping underneath. Apply paint carefully and remove the stencil promptly after painting, ensuring the paint does not dry and stick to the stencil.
