I charge an hourly rate out my shop for anything mechanical or body/paint and give a rough estimate for how many hours may be involved..mabe show him where you are at and say the truck needs alot more work than the initial $3000 quote and show him why that is and give him the option to either put most of it back the way it was *after finishing the paint* or proceed forward with an hourly rate on anything else? The shop rate around where i live is around $90-$100 hour at most shops..i charge friends $30h and walk ins $60h..my friends are getting a screeming deal as that just covers my time, just a few ideas to throw your way..good luck and try not to get too stressed ;)
