I am in the process of doing this. First I wire wheeled the manifolds. Then I used the rust oleum srripper/ conditioner. Then the high temperature rust attacking(?) primer and then black for intake and silver for the exhaust manifolds. I have done this in the past, but have not used the stripper or rust oleum, just another high temp paint. The intake always stayed black, not so much with the exhaust. I am hoping the rust prevention aspect works better.
