windscreen graze repair

[marinabrid]

evening all
living by the coast we get the seagulls who crap all over us at this time of year. now it dries like acid cement if your not quick., so some was baked on the windscreen    foolishly the wife use a sodding fine sponge pad with that rough stuff on, supposed to be non scratch for her pans.   
well its grazed the glass, like a graze on your arm ,  any remedies    googled suggest toothpaste ., then there paste kits you use with a drill pad.
any suggestions welcome.    this is a new windscreen as well.   i am going to use the pad on her backside

afaik even the paste d/glazing firms use to take scratches out of there units still leave fine marks.
wonder if something like tcut with a polishing cloth attachment will help?

3m probably do something suitable. Look on YouTube for headlight restoration videos. I assume it would be the same process.

The stuff you need is Cerium Oxide powder. Can be found online via the usual sites.  Mix up into a paste and rub like hell ... mechanical assistance is best.  It takes an awful lot of polishing depending on the depth of the scratches.

I think we've got some of that in the garage, my Dad bought it yonks ago for polishing a set of telescope reflector elements he was going to grind flat himself!
