TotalBoat Wet Edge topside paint can be applied to acrylic paint that is in good, serviceable condition, that has cured for at least 5-7 days under normal curing conditions, and has been lightly scuff-sanded. It should be understood that the acrylic paint underneath is a softer, more flexible coating than Wet Edge paint, and the performance of the Wet Edge is dictated by the condition and surface preparation of the acrylic paint.
