wow... didn't realize it was so expensive to have a shop do it. the reason I am looking into replacing them is because the previous owners of the bronco set it up as a tailgate vehicle to wine and dine clients before football games. It was painted rams blue and had gold stripes over the windows. When I got the bronco the stripes had already been removed from everywhere but the roof. The problem is that they used a random orbital sander on the glass to either make the vinyl stick better (doubtful) or to remove the stripes that were on the glass and residue (lazy). I am currently trying to sand the swirl scratches out, but have my doubts that it will work.
It appears they used about 150 grit to do the damage. I have tried rubbing compound first, then 1000 grit, they only polished up the high spots. I am going to try to pick up some 600 ish grit tomorrow and see if I can do some good and go from 600 to 1000 and then rubbing compound.
worst case I replace the windows (which I am considering already)... all I am losing by trying to work the scratches out is some time and some money on the sand paper...
Thanks for all the input everyone much appreciated.
