hey my exhaust is rusting, and i was wondering if you could give me a suggestion to a high temp primer... thanks

 

I had the same problem with a RRM exhaust I got a while back. I used rust remover I got from pepboys and then used highheat black engine paint to cover almost everything but the tip. It's fine now, just watch out in the winter when they do a lot of salting. Makes it rust a whole lot faster.
