On the left hand side (right hand drive car) of my windscreen is a scratch that's been done by the end of the wipe blade, it's about 2-3" long and about 1" wide, looks a bit like some sandpaper has been caught under the wiper blade.
Is there a product on the market that will let me polish scratches out of glass?
It works very well on clear plastic (an old modeller's trick from when I was a kid, IIRC)
Would have thought that glass would be too hard, though - I'd look at a specialist glass polish, myself (Autogylm as a first try, or something that a glazier would recommend).
& do a search for "glass polishing kit". About £20 & works pretty well - I think the cutting agent is called Cerium Oxide IIRC.
You use an electric drill & you have to be careful to keep it moving & keep the thing wet enough so that you don't get a localised heat build up which can weaken the glass.
I used it on the inside of a big aquarium with good results & that's made of plate glass which is very hard. It took quite a while though - over an hour to do an area about 9" by 9". I've seen the same kit advertised for polishing windscreens. All that said, as a general rule, if the scratch(es) are deep enough such that you can feel them with a fingernail then they are reckoned to be too deep to polish out.
