Question for metallurgists, chemists, or maybe painters....

I'm not painting aluminum. It's not rusty, it's galvanized.

You talkin' to me?

Then who the hell else are you talking... you talking to me?
Well I'm the only one here. Who the **** do you think you're talking to?
Oh yeah? OK.

Try epoxy

I would have just painted the wheels and called it a job....We used to think my uncle was crazy. If he didnt have time to wash his car he'd pull up to a hose, rinse and wipe the wheels proclaiming that when the wheels were clean the whole car looked cleaner...and darn it if he wasnt right.....

Tried epoxy paint on the fenders which are galvanized. Flakes off very easily. Been doing a bit of research, think I'm onto something that might work....

Yeah, nicer wheels would help.

they are my pushers for chemical stuff, they are not resellers, they are producers, they know their stuff

scroll down to: ZN epoxy primer and you will read (my liberal translation):

[ZN Epoxy Primer is a two component epoxy primer passivating and anchor for metal surfaces. It prevents and hampers the spread of rust and has a powerful adhesion to metal surfaces. Particularly suitable on aluminum and galvanized steel.

Tested on alu.

We used to strip and paint galvanized school buses in the 80's. Acids that etch the surface allow the paint to stick as good as it can. Check out the link HERE it might help.
