buffing scratches off glass

where the damage is its part of the window where the vision is distorted anyways. its at the top on the L/H side. apparantly 3M makes a glass buffing kit called trizact. as far as distortion is concerned, i have buffed out scratches on aircraft acrylic plastics. you have to buff out a large portion of the glass, not just where the scratch is otherwise it will distort. we put a paper grid pattern on the back side of the glass when sanding and buffing. if the glass is getting distorted you can see it on the grid.

i will probably buy one of these kits, as it can also buff out little spots from welding and grinding too, as well as hard water stains on glass.
