$7000 paint job
I did mine at home, in my 16x20 garage. It's base / clear, and I have about $1300-$1400 in it, and that includes, paint, primer, clear, body filler, sand paper, air powered longboard sander, etc.
This was my first attempt at painting a car. Is it perfect, no, but its WAY better than I ever thought it would be. I spent a lot of time getting all my the bodywork just right, and a ton of time colorsanding the clear and buffing it out.
I think it looks fantastic, and I never could have afforded to send it out for a 6k - 10k paint job.
I learned a lot, it was fun, but a lot of work, but I can say I did it all myself. Will I do it again, probably not. Getting to old for that type of work, and it eats up a lot of otherwise free time.
If I ever switch cars, or add another old car to my collection, I'll buy an already finished car.
At this point in time I'd rather just pay for a nice car instead of spending all my time and effort building another one.
