Used maroon scotchbrite to scuff the parts to be primed. I got everything done except the inside of the skins, which I will do later. I will go over everything with acetone or thinner to clean and prime today with NAPA 7220 self-etching primer (rattle can). I just can't bring my self to 2 part epoxy pieces that already are corrosion protected (alclad). There are several RV builders using the 7220.
