That may work on slight scratches but I would be surprised, but delighted, if either of those two would work on the micro pits caused from air born particles when cruising at high speeds (excess of 120 mph) but if it does let us know. Two years ago I ended up with a very pitted windshield going across Nevada between 140 mph and 150 mph for a span of about 30 minutes, since then I don't exceed a 120 mph anymore.
