The paint I mentioned, I bought at the local Ace. I don't know if it needs primer, but with a name like Rust Stop, I doubt it.
My compressor is 21 gallon, 3HP, 125 CFM.
My gun is the following: Spray Gun

The guy at Harbor Freight said it would work great with my compressor.

Also, is a quart enough paint to do my car, or do I need more than that?

Thanks hotrodpaint, you are a stand-up fellow!
