I just took delivery of a new Tahoe LTZ. It looked perfect but when I washed it, I noticed while drying it that there is a 4" long "crease in the roof in between the windshield top and sunroof near the XM antenna. There is no scratch in the paint. The dealer thought it could be from a stamping of the sheetmetal and offered to have a Dentbusters person work on it. I was wondering if I should just leave it alone or have Dentbusters try to remove it. My concern is what if they have to take out the headliner, etc... and maybe it could be worse after all is said and done. What would you do if this was your truck? Any input is appreciated. Thanks, Paul
