Dale's effort just confirms the comments I made about painters in another thread.
Cost of $2000.00 including a gun/sanders/masking etc. and I'd guess the plastic film to protect his spray booth.
That leaves change of $13000.00 from a $15000.00 pro spray job. What's a pro painters hourly rate?. Usually it's the laborers/apprentices who do the bulk of sanding and blowing the primer on, so lets say $60.00 an hour.
Give one full day to the pro to blow the final coats/stripe etc.
So .. $13000/$60.00 = 216.6 hours ..... or approx 5.5 weeks full time work on the car.... I don't think so.
My comments are justified.
