The alodine I have used to coat aircraft parts gave a yellowish tint

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.
