$7000 paint job
might i add, many community collages have paint and body classes. I'm in both paint and body at my local community collage right now and while i need more practice before i relay get started on my car, my body working skills have improved greatly.
as far as cost goes. i'm probably going to spend 2-3000 in just paint (house of kolor shimrin 2) but as long as i'm in a refinishing class i have access to a heated paint booth so the cost to paint is 0.
so i guess i'm saying if you want to paint your car your self check community collages around you for paint and body classes and e mail the instructors asking whether or not they allow students to work on projects.
