Epoxy & Polyester

Although polyester primer can stick to bare metal, it is the best to spray a light coat of epoxy on your bare metal areas first. **A major caution! The epoxy needs to be very dry first, it will cause the polyester to crack and delaminate from it if it's not dry enough. I'd let it sit for at least two days of you can. And then just hit it with a red scotch brite before you spray polyester.
