What is RPM?




A treatment for bare metal to keep it from rusting.

I read the independent labratory test. I was particularly impressed by the abrasive test, even their sandblaster didn't remove the stuff!

So, can you paint over RPM? If not, how do you prep an RPMed surface for paint? Will lacquer thinner or wax & grease remover touch the stuff?

Does it work just as well on less porous surfaces? Maybe I can put it on my polished aluminum and not have to re-polish as often. Might be nice over chrome also. I hate when a chromed part starts to rust.
