We took our truck to Q as we had a sunroof leak and we were getting ready to sell the vehicle. 2 other body shops failed to stop the leak and left some ugly evidence of their attempts. QWERKS found a caulk that matched the weather stripping and if you didn’t know what you were looking for, you wouldn’t notice it there. I took the truck through the car wash tonight to test it and there were no leaks. We are SUPER impressed with their work.
