I usually charge 100.00 for a regular basic paint job with clear coat. Time is based on what your using. Lacquer? Clear coat? say 2-4 hours prep body and body work, 2 hours sanding final primer, 1 hour base paint, 4 hours decals? 1 hour final clear coat, 2 hours to rub out or are decals on top? Plus 2 six-packs for the decals! your not making great money on a decal job like this unless you charge 200.00 to 250.00 most people will not pay that but, it's alot of work unless you like the subject to do for the fun of it. Need more info on what your using and what order
