Tinted a Jeep Grand Cherokee 2 wks ago. Forgot which year probably 2013-2015. Customer came back and showed me his door windows and and rear side on trunk. They all look like snake water spot line. First time I ve seen it. Any ideas? Rear hatch is ok. I doubt it s a glass defect. On the rear side trunk where tint only go to the matrix line. But those water spot line runs all the way outside the matrix line too. So I m gonna remove one window s film and re-do just one see what happens by next wk.
