Abstract
Corrosion resistance of anodized aluminum surfaces is improved by conditioning the surface with a low molecular weight (2-7 carbon atoms) alcohol, and sealing the surface with long chain (10-24 carbon atom) carboxylic acid at low temperatures below about 35-50 degrees centigrade, the alcohol being a solvent for the acid.
