good advice from everyone. Dont bother. ESPECIALLY since he want you to color match his car. (and the car isnt here with the painter) BIG red flag. Give him a extimate on the paint job from 3 local guys and tell him his best bet for a good match is to take the car to the painter…not just go by color code… that should help convince him.
Discount your price a bit for a little extra push and get rid of these things and extra BS work.
