Cause:

  2. Incorrect use of an infrared dryer.

Correction:

  • Sand the damaged area and redo the repair.

  • Before applying the putty, it is best to clean the existing paint surface with a silicone remover. If the paint color fades, sand the existing paint surfaces to ensure a good adhesion surface.
