TotalBoat Wet Edge topside paint can be applied directly over TotalBoat Aluminum Boat Paint, but it is extremely important that the Aluminum Boat Paint is in good condition, with no scratches or peeling.
The TotalBoat Aluminum Boat Paint must be cured for an absolute minimum of 48 hours, and lightly sanded or scuffed with 320-grit sandpaper or a Scotchbrite™ pad prior to applying TotalBoat Wet Edge. There can be no bare aluminum exposed when applying TotalBoat Wet Edge. TotalBoat Wet Edge does not have the corrosion-inhibiting properties that Aluminum Boat Paint has, which help resist bubbling, peeling of the paint, and oxidation of the aluminum underneath.
