The gridwork on the inside of the glass has a few blackened areas on it, maybe the size of a penny total, and since I'm selling the house would like to make it look better. I see the part, AP318927, but is that just the film not including the metal grid? Or is the grid actually contained on the film? Do I just peel off the old one and what type of cleaner would be safe to use before applying the new film?
Thanks for any help you can offer.
