[QUOTE="PSG-1, post: 395941, member: 6937"] Paint flaking off has everything to do with improper etching and priming of the aluminum. Aluminum instantly forms an oxide on contact with the air. This oxide barrier is what protects it from corrosion. Unfortunately, it's also what prevents paints from adhering correctly, at least not without etching with mild acid, and/or the use of a self-etching primer like zinc chromate. From what I understand, the EPA has made paint manufacturers do away with zinc chromate primers. Unfortunately, those are the most effective self-etching primers used for aluminum, and several manufacturers are encountering this problem with paint jobs. [/QUOTE]
