Any one ever use the 1 galon cans at home de pot for painting a car? I know they are just a few colors to pick from but at $27 a can will it make a 1/2 respectable paint job on a $500 car?

Any tips for thinning it and spraying it? Does it need any primer if sprayed right on fresh bare metal? Reading the label seems no primer or clear is needed seems to be a cheap way to make a cheap car look ok for a couple years
