The grey anodized aluminum rub rails on our Hunter 34 are pretty roughed up and need some welding repair in a couple of spots. If I can't figure out how to clean them up they will be the worst looking part of the boat when we reassemble everything. Since having a 32 ft long piece of aluminum anodized or powder coated is pretty much out of the question does anyone have advice, preferably based on real-world experience, about how I might get these things looking good? Would epoxy primer and some high quality 2-part paint hold up and be repairable down the road? Anyone tried it? I've used the POR-15 products on steel during auto restoration projects but not on aluminum. Anyone have experience with POR-15 on aluminum?
