    That I didn't know. But, oxygen is necessary in order for rust to form. By eliminating O2, seems the corrosion problem would be solved? (again I complete my thought with a question mark

    Powder coat or paint, my thought is the inside of the frame will last longer than the outside. Even if it is not treated. The more exposure the more the problem, right? I guess it depends on where you live on making the decision of inside corrosion protection.
