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.
After James' post I did a little research on protective aluminum
coatings relating to the aircraft industry and there are hordes of
them. There is even a Boeing T-9 that you spray on and is supposed to
penetrate all the nooks and crannies and turn to wax in 5 or 5 days.
(sounds like a super chain lube :-)
