I just bought a rear window off EBAY for my 50 Chevy coupe that was supposed to be "mint" so it shows up and there are several small scratches and one pretty deep one. What is the best way to get them out? I thought about calling an auto glass place locally to see if they'd do it, but I'm not sure they would with it out of the car, or even if that's the best way? any advice?
I used Eastwood's cirilium oxide (sp?) on all the glass on my '55 Chevy. All the glass was removed at the time. That enabled me to do the inside easily, but made no difference on the outside surfaces. The stuff did a great job removing all the overspray/tiny rock chips/scuzz, but was useless for any scratches that were deep enough to catch your fingernail.

000 steelwool with some glass polish you might have to buff it out if they it is real bad especially mineral deposits!! I have not tried eastwoods new disc yet you should give us some feedback if you go that route.. It would be intresting to see?? I usally have bad luck with there products
Trust me when I tell you I have had dealings with Pilkington, the glass manufacturers for 20 years, Oxide polish is all there is! If you can feel the scratch with your fingernail you own it for life. Nothing will take the surface of the glass down without leaving a huge 'bullseye' circle distortion, I had a w/screen that I worked on one deep scratch for 2 days solid using Pilkington supplied polishing buff and wet Oxides...... Zip - Nada. Any polish compond will only ever remove a 'bruise/rub mark' on the surface of the glass.
Cerium oxiode with a felt polishing wheel. Use water to keep the glass cool and to hold the powder. This should get the light scratches out if they are deeper you may have to sand them down first. Just like polishing anything else. Always use water. The glass should not be allowed to get too hot its bad for the tools and the glass.
WRONG. there is a new system that works wonders on tempered glass, with no distortion and it works with heat. (I wouldn't have believed it before I saw it done) but it's probably cheaper to buy brand new glass. if you have a rare or obsolete glass it can be saved but usually runs $300+. the last one I had done cost $600 but it was not available at any cost steel wool scratches glass. and cerium oxide will work on laminated but only marginal on tempered

Being an amateur gemcutter as well as a car guy I know there are abrasive and polishing discs that will easily do glass. As I recall, glass has a hardness in the 5.0 - 6.0 mohs scale of hardness which is relatively soft in gemstone terms. In the Faceting class I took we practiced making gems from green coke bottle glass. The question is whether you can get a coarse enough flexible disk mounted on a variable speed grinder (using lots of water lubricant/coolant to take the scratch out then progress to the polishing discs. I'm convinced it can be done I have just never tried it. Check out Graves Lapidary Supply Graves Company Online - Lapidary & Jeweler Supply
