Prime glossy surfaces to promote adhesion of the top coat.
There are three ways to prime a glossy surface:
1. Use a latex or oil-based primer formulated for glossy surface adhesion.
2. Use a liquid deglosser such as Prepaint, following all label instructions.
3. Go over the surface with 200 grit sandpaper. The scuffing will help the new paint adhere. Wash the surface with TSP, rinse with water and let dry.
