The Stovebolt Site Forums The Shop Area Paint and Body Shop Recommend a good epoxy primer

Thanks for all the suggestions. A couple questions
1. If I use PPG or SPI epoxy primers, what would be a bulletproof topcoat from these companies? I am using this on my axles, frame and other suspension parts.
2. On some of the smaller parts I used a rattle can of 2K Urethane Primer to keep the part from rusting. What would be a good topcoat for this type of primer? Or...
3. I know I will get slapped for asking this, but can I spray epoxy primer over 2K Primer? I would scuff the metal until the high spots were bare metal leaving some of the 2K in the low areas.

Thanks.
Michael
