TotalBoat TotalGold paint will not form a great bond to powder coated surfaces, even if the substrate has been sanded first. To promote the best adhesion, sand the surface with 180-grit (or coarser) sandpaper, and apply an epoxy-based primer, such as TotalBoat 2-Part Epoxy Primer or TotalBoat TotalProtect first. Allow the primer to cure for 5-7 days, sand with 220-grit sandpaper, and remove any sanding residue prior to applying TotalGold paint.
