Hello. Last summer I purchased a 2003 Crestliner Rampage deck boat. There is some corrosion around the bolts on the transom, and I'm wondering what the best method is clean it up. The plan was to sand it down to clean aluminum and repair with marine tek or jb weld and then paint. The other issue is the plywood transom needs replaced. There is dry rot at the top, and it was leaking water around the transom assembly. The current plywood is painted, with the inside exposed. Do I paint the new plywood, or encase it in fiberglass and epoxy?
