[quote=Texas-Tri]Oxidation on aluminum will cause paint to flake unless you prime it properly. I just repainted my black anodized (and very scratched up) cross beams. I sanded them and then washed the surfaces with vinegar (the acid in vinegar removes any oxidation) and then as soon as the vinegar dried I sprayed on self-etching primer and then Rustolium and it looks great now. It's a cheap and easy way to do it. We'll have to see how well it holds up over time.
Good luck![/quote]
