So " Pledge " might be considered a restoration remedy. I have a three year old VTX winshield in the barn shed, I'll try it out on. It has lots of spider-web scratches.I used pledge on my '84 Interstate at the Wing Fling some years back just before the show & shine. Took a bit of time and a lot of rags (and a whole lot of elbow grease), but it took out all the spider-web scratches and made the screen look almost new rather than the 6 years and 100k it had on the clock. Took the 1st prize in class so it wasn't just my opinion involved.
