Al Conversion coatings / belly pan
Curious if anyone has experience using an Alodine conversion coating on their belly pans. I've seen a few notes about it in belly pan threads but no results reported. I am hoping to save a few bucks, but will resort to anodizing if it is still superior.
I bought the chemicals from Wick's in an effort to try it. My sample trials so far haven't made a visual change, other than the etch brightener that goes on first. I do not get a tan or gold tint. I am hesitant to trust it on the belly pan without more data.
Thanks

Alodine = Hexavalent Chromium
I used it on some mag wheels for my Zink and some alu parts and it worked well with etch prep. It's chromic acid and ferrocyanide.
It's quite poisonous. Chemical vapor mask, goggles, rubber gloves. https://www.aircraftspruce.com/catal...ine1201sds.pdf
