Finally got the Jeep painted and did it for less then $50. Cheap XORust(comparable to Rustoleum) enamel on clearance for $14 a gallon. I wouldn’t recommend painting every car this way but for me it worked well. You don’t need expensive equipment, just take your time and remember what your vehicle will be used for. I used less then one gallon of paint a few OZ of Acetone and even less hardener.

This is not the exact hardener I used but should be the same. https://amzn.to/2VJlPb6
