Yes you do. Some epoxy mixes may also emit an 'amine blush' that needs to be removed before top-coating with another product. Some require a wash with a cleaner and some a wash with a solvent, but I don't use Gluvit so can't advise here.Riverman said:I coated the bottom of my aluminum boat with Gluvit and it's hard as a rock now. Do I need to lightly sand it before painting with Duralux aluminum boat green?
