anyone recommend a spray on rust removal product for exhaust headers?

I've heard of evapo-rust working really well but it would cost a ton to get enough to dip the entire header into for 10 minutes

Try a product called Ospho - will convert the rust to iron phospate (black) if you leave it on or will just eat off the rust if you brush it off after letting it work for a while. The iron phosphate coating is quite durable and will resist further rusting. Also work well on any rusty body parts as a prep before primer. Sand the rust smooth but do not remove to bright metal as the Ospho needs something to convert. It will not protect bright metal.

thanks for the advice, unfortunately I called just about every home improvement/paint related store and they dont carry it :/

Por15.....they have rust removers and high heat paint for headers that will resist rust. I have used the regular Por15 and the stuff works.....

to find ospho, go to a marine supply store, it is a green liquid in a clear container, also, if the rust is not that bad (surface rust), Flitz is a great product to use; also found at the same store.
