Thanks everyone for your input, here is what I'm going to do. I'm going to prime the whole truck with a epoxy primer. Then I'm going with 2 stage paint. I'm a cabinet and furniture maker. So I'm guessing I'm going to try to match what do with wood. I have used single stage stain, with the poyl in the stain. It can look good but nothing is better than a good laquear finish. So 2 stage it is. Here is a picture of a bar top I just finished today. My work truck is getting more expensive everyday.
