What is the method for removing paint film?
2 Answers
The methods for removing paint film are as follows: The mechanical method involves using a specialized electric or pneumatic grinder to remove old paint. This method is generally used for small areas to reduce labor intensity and improve paint removal efficiency. When using an electric or pneumatic grinder for paint and rust removal, if a hard grinding head is used, the grinder's rotating shaft must remain perpendicular to the paint film surface; otherwise, deep grinding marks may be left on the metal surface. The chemical paint removal method is mainly used for large areas of old paint film removal. The mechanical method is time-consuming and can cause deformation, whereas the chemical method saves time and does not cause panel deformation. The chemical method primarily uses paint strippers to remove old paint layers, but these strippers have strong chemical properties. Before using a paint stripper to remove old paint film, ensure the surface is free of dust or dirt.
As a seasoned professional in car detailing, the approach depends on the film material. For PVC films commonly handled in our shop, it's best to work on an overcast day. Fill a spray bottle with warm water mixed with dish soap, thoroughly wet the film surface, and wait about 7-8 minutes until the edges soften for easier removal. Start by gently lifting a corner at a 45-degree angle to the paint surface, peeling slowly to avoid adhesive residue. For stubborn spots, apply medium-heat from a heat gun for 5 seconds before trying again. Remove residual glue with industrial alcohol, using tar remover for any tar spots. Finish with a full wax application to restore shine.
