I guess it was designed as a preservative, not a beautifier :-) Both form a barrier to further corrosion, but alodine is a conductive coating where as anodized is insulative. Also alodine is easy to scratch, where as anodized finish is harder. Alodine is available in different colours, IIRC. Ah, I didn't know that. I never actually used it a great deal but back then it was a yellowish and rather thin liquid that we dipped or painted any raw machined aluminum things we made with. I'll research it a bit more. If there is a clear version then it would probably work well. -- Cheers, John B. |
