[FRPGUY]

All these liners are great for street driven cars, but race cars it's not so good ! If and when you crash and need some fiberglass repair, all that liner has to be removed to get a clean surface to stick new fiberglass to. I've spent hours removing liner material from the inside of fender wells. Time is money! Heat works best, but the fumes just about kill you! Even flat black paint has to be remove to get a good repair.
