Is there a way to buff some scratches out of an old windshield? Picked a top section up and there are no cracks, but just as many scratches. On coming headlights are hell! :-/

There used to be a glass place down the street from me. The oldtimer there used to swear Lemon Pledge furniture polish was the ticket for scratches in plastic windshields. I never tried it and he's gone now but might be worth a try.

Lexol, has a fine polishing compound, (light scratches) for lexan windscreens.
& a heavier compound for heavier.
Still must finish w/the fine compound..

I had the same problem when I was racing circle track. Towards the middle of the season the Lexan would get so scratched from wiping it down that I could hardly see under the lights at night. I tried all of the cures to fix the scratches and finally gave up because no product did what it claimed to do. I ended up using Mcquires #7 before each race to reduce the glare and swirl marks.

If you find the miracle cure, let us know.

Vintage 'beaded' windshields and modern reproductions are cellulose acetate. The can be worked out with 2000 grit wet-or-dry paper, then finer and finer compounds with the result dependent upon your perseverence.

Modern Lexan shields, normally sans bead around them, often have a thin layer of a scratch inhibitor that doesn't like abrasives. If you accidentally buff through it, you might as well take a pressurewasher and peel off the rest of it. Then it also will buff with finer compunds and glazes.

When custom-cutting shields from Lexan sheet stock, I found that after sanding, a quick-cutting 'rouge' for buffing the edges was common kitchen scouring powder, like Babo or Comet.

One barnyard trick that I still use daily on my blast cabinet windows is a wipe of acrylic floor wax, like Glo-Coat. It can make a dramatic difference in visibility through damaged plastic.......until it rains!
