I had some scratches in my windshield in my 46 coupe. They were pretty fine, caused by a scotch pad on the back of a sponge. Don't ask. Anyway, I purchased the Eastwood product. I was unsuccesfull in my attempt to remove the scratches, although I will admit that since the windhield in a 46 Ford is two flat pieces of glass, I decided replacement would be easier. If I were not so lazy, or had the windshield been more expensive, maybe more effort would have had better results. Joe
