Paint set up recommendations?

You'll be hard pressed to find a compressor that's capable of spraying an entire car for $600. Remember you're going to have to spend hundreds just to keep the line clean and dry as well.

Everything needed to paint really starts to add up after a while. I wouldn't invest in the tools unless I planned on painting at least 3 cars at some point.

I have painted 3 cars and can run a sandblaster cabinet all day with this (it does run constantly so you have to watch it on hot days)
