How To Use Expanding Foam To Re-Build Your Car
Step 6 – Sanding and Using More Body Filler
Sanding the body filler can take time, and one should start out with a more coarse sandpaper to remove the excess filler. This process takes a much longer time than the other steps, so close attention and patience is required. The second layer of body filler should be used to fill the holes and grooves left behind by the coarse sandpaper. After this step has dried, sand with a fine-grain finishing paper; this step can be repeated as many times as needed to reach a smooth surface that is ready for primer. A light coating of primer should be applied using a continuous to avoid running.
Step 7 - Primer Before Paint
The primer will dry after a few hours, but most prefer to paint the vehicle the day afterward. Be sure to gently sand the primer with very fine sandpaper to make it as smooth as possible. It is important to research the exact color match for your car’s original paint. Most auto stores can help assist in finding the right paint that will match the existing paint. Once the correct color of paint is found, one should be sure to paint in longitudinal motions so that the paint is applied uniformly to avoid runs. Allow time for the paint to dry between coats. Two to five coats of paint should work well.
