Detailing Dynamics HANDS DOWN!!!! Located in Mineola and they do all hand cut pieces. Don't get the wrong idea, their work should be in a museum! I have seen numerous types of clear bra installed by numerous pros. Theis is by far the best! You will not even know it's on there until you are about 2 ft away!
As for cost, do you want the best looking clearbra or the cheapest one. If you are looking for the cheapest, forget DD. If you want the best, give them a call to discuss rates. It all depends on how much you are going to get done. There is a reason why they handle swo many exotics and are the place to go to when someone else else messes up a car! You can google them to find their website or you can PM me and I'll forward it along (DOn't think I can post it here)
