These practices describe procedures for the preparation of hot-dip aluminum surfaces for painting. Two types of surface preparation are included: solvent cleaning and chemical treatments. Solvent cleaning of the surfaces may be done by any of the following methods: manual swabbing or dip washing with a solvent such as mineral spirits or high flask solvent naphtha, solvent spray cleaning, and vapor degreasing in special equipment. On the other hand, surface preparation of aluminum for painting may be achieved by any of the following chemical treatment methods: use of alkaline cleaners, use of alcoholic phosphoric acid cleaners, use of acid fluoride deoxidizer, crystalline phosphate treatment, amorphous phosphate treatment, carbon chromate treatment, amorphous chromate treatment, and acid-bound resinous treatment.
