Ok sorry if this is in the wrong section, I couldn't find much on this topic.
I'm planning to get my 67 Notchback ready for paint next year and will be removing the front and rear windshield and replacing the rear( very scratched and old bad tint).
The side windows have what looks like light to medium scratches that were probably due to rolling the windows up and down with old bad felt.
To save money I plan to buy a 50$ glass polishing kit and spend a weekend doing my best to polish the side windows.
Has anyone on here done this?
I've watched a couple youtube videos and it seems laborious but doable.
 
I just did it on my convertible back glass.

It does work but does not take out deep scratches by itself. I was able to polish a big scratch to be smooth but it was still there.

I was just using the powder and a small buffing wheel

Well if I can get the side window scratches to look 50-75% better than they look now I'd consider it a success. I plan to buy this kit online ,GP28004 Glass Scratch Removal Kit, glass restoration, glass polish, xNet System.
At 50$ it's better than buying 2 windows.
I'll probably do it right tu after Christmas and I'll post up the before and after so maybe itll help others who have contemplated this route, thanks for the response.
 
I think the real win/lose deciding factor will be how many hours I have to put into it to get good results. If I can get good results on 2 windows in 1 day I'll call it a win.

This is what I used.
Looking forward to your results

This is what I use as well. It will work. Be cautious to keep the glass cool as possible. Take breaks every 5 to 10 minutes and cool with water from a garden hose. Do it in shade or you garage not in direct sunlight. Inspect with a flash light.

If you get it too hot it will delaminate and/or discolor.
 
Do it on a cool or cold (shady) day, take your time. Use your hand/fingers to touch the glass to make sure it's not getting hot. Use a spray bottle of water to keep it cool. Work over a large area ( blend, like when you're doing body work) so that you don't dig/make a valley/depression. Be prepared to make a mess as the polishing compound goes all over the place. If you do it with the glass in the car you have to tape off everything with paper or you'll be cleaning that stuff out of every nook and cranny for months!! You're clothes will get stained so wear and apron. Please don't ask how I know???

That applies only to laminated glass. Only the windshield is laminated (sheet of butyrate plastic in between two sheets of glass); the rest of the glass on the car is tempered, so there's nothing to delaminate or discolour.

But heating it too quicky could make tempered glass crack????
 
The disks I used were about 1.5 inch in dia. The YouTube's I watched said to use as little water as you can. I just used a variable speed drill and felt the spots from time to time. Nothing ever over 120. I would not spray cold water on hot glass it will cool down fast enough.

Also a felt tip marker on the opposite side of the glass to mark the spots your working on.

Great tip on the market idea.
 
I did my windshield. Definitely worth a try on your side windows. But others are correct...it is messy!!

Check Ebay. There are kits with a quantity of the felt discs for a whole than $50.00
 
If you're not in a hurry you can get the same kit very cheap ($15) straight from China, that's what I did.

Windshield glass is Laminated and not tempered. Laminated glass is a lot softer than tempered glass.(on a hardness meter tempered tinted glass is considered a 90. laminated tinted or clear is 65 in hardness or Durometer ) tempered glass is under strain all the time after it's been tempered. insides want to come OUT. imagine a balloon, poke it a little and it won't break, poke it more (deeper scratches) and it will break. But it can be polished a bit without hurting the surface tension. If you can catch the scratch with your fingernail , as the saying goes with older glass plant workers (me for one), "it ain't coming out of there" You can minimize it on tempered glass (or blur the edges somewhat) by using jewelers red rouge but it won't go away if you can feel it. And don't concentrate on one area you have to feather it just like paint. Laminated windshields react a lot better to polishing than tempered side glass.

Only if there is a weak spot on the glass Or you concentrate it only in one area. we used to take rear Dodge minivan window (backlight) and have a 350lbs guy jump on the rear tempered window laying on a rubber floor mat to show how tough the tempered glass was. Glass would go almost flat and then rebound pushing that guy off the glass and about 5ft in the air but didn't break. (took about 4 guys to catch him and keep him from falling just like a trampoline) But one light rap on the edge made the piece shatter

most excellent point.
 
the scratch I polished out was a windshield wiper scratch and I used a 5 inch wool like wheel in a hand drill. it worked real well. I have not tied to use it on side glass or a rear window yet.
 
Back in my dealership days we simply used Meguiars buffing compound and a 7" buffer.
