Windshield is in and it was relativly easy, did have everything masked off and maybe a little overboard but wanted to be safe. I could have uniformally applied more 3M than I did so that I did not have the voids, would have been better if it oozed out all the way around.June2019X2 002.JPG. Any place that it did oozed was easily cut away after it cured both inside and outside. I then ran a bead of black silicone around the edge (after masking off everything again), that filled in the gap and covered where there was not enough 3M.June2019X2 005.JPG. I would not be afraid to do it again.
