MOPAR faithful: I'm trying to recondition the air cleaner on my 1974 Duster slant six motor. It's rusty, cruddy, and the paint is coming off. Anyone know of a process that'll remove paint AND rust, while at the same time leaving the factory metal coating on the air cleaner? This coating looks like it was galvanized, but it was't of course. I don't want to bead blast it as this would take off the factory anti - rust coating. Any ideas? Maybe take it to a place that can dip it in a solution that removes paint and rust, but leaves the metal coating. Ideas?
 
Got any pictures? I've never seen a galvanized air cleaner. If there is rust then any preventative coating is compromised and you may not be able to just re-seal those locations. Typically its easiest to strip all completely down to bare metal, clean and re-seal it.
 
If the rusty spots are out of view, you could wire wheel, treat with a rust converter and topcoat. If not, have a plating shop strip and re- plate with your choice zinc chromate etc.
 
Thanks for the mention @Blind Squirrel. I've restored dozens of old air cleaners through the years but don't recall ever seeing a "factory rust coating" on any of them.

Perhaps a vinegar / electrolosis bath will clean it up some (I media blast).

@cruiser, just one question though. Why would you want to try to preserve this anyway in light of the fact it's now all rusty? It apparently didn't work or you wouldn't be fighting rust now.
