Good point. I forgot to mention I have some rust converter. Which primer should I use over the rust converter? I plan to use the Moeller engine paint as a top coat. The only primers they sell are the Zinc Chromate and the pure zinc (advertises as cold zinc paint). Is it ok to use the Zinc Chromate over the rust converter?
