It could be Alodine as well. It was pretty yellowish looking to me....dusty
gold too? (heck, I'm terrible with colors) In any event, it leaves the
aluminum (if initially bare) a yellowish hazy color. I purchased it locally
at an auto body store called Auto Paint in Burien, WA (close to Seattle).
It should be readily available at any auto body store where Dupont products
are sold.
