That sucks Tony!

I'm smutting the shop's name every chance I get around here, they fukked me on some seats as well, had to pay my old guy to redo them, and had to eat it as I couldn't make my customer pay for the seats twice. I'd say it's going to take 8 hours @ $85.00 per hour labor and $147.65 in materials, that ought to more than cover your time and headache. With this being found I think I'd be looking over everything they did with a fine tooth comb................
Let me know if I can help, I can always whip you out an invoice from The Hot Seat, we're a fiberglass company after all...............
