Rick, I can't help but feel that you are going to regret a cheap paint job. Before you commit yourself too much to rattle cans and drained rattle cans, consider whether you should just do it right. There are economical paint lines out the (summit has one and I think eastwood too) It's easy to pull a trunk to do this, but, before too long you are going to be in the area of engines and interiors. I just don't see the durability or sheen or coverage coming from rattle cans. My vote is, wait till you can do it right.
