Hello!

Alodine is the chemical conversion of the aluminium surface. It means that the surface to be treated is free of grease, paint, ... The best is a good degreasing, very good rinse and Alodine. After the Alodine treatment, the surface need to be rinsed twice : first with tap water and secondly with demi-water to remove the salts traces.
