Restored GT wheels (basic how to) (Page 2/2) IMSA GT MAY 25, 07:23 PM I have to agree that any type of bare aluminum should have some sort of self-etching primer. When we paint aircraft, we use Alodine to protect the aluminum and give a great adhesion surface for the paint. Painting bare aluminum is asking for trouble in the long run. Beautiful job on the wheels. I'm glad you were finally able to purchase a set. Skybax MAY 25, 10:56 PM Thanks, we'll see how they hold up.
