How does one polish small scratches out of glass?

[resq302]

Is there a way to polish a very light scratch in automotive glass?  The reason why I am asking is that there is a very faint scratch that I can not even catch with my finger nail on the windshield of our 69 gtx vert.  It seems like the wiper at some point had made contact with it and since it is an original correct date windshield, I would like to try and save it if at all possible.  It could even very well be just the aluminum from the wiper blade that transferred over onto the glass.     What would the best way to try and get this cleaned up?  White polishing compound?

I'd take it to a glass shop, they have the needed polish to take the scratch out, or at least reduce it.  I've heard too many stories about glass warping when polishing too much but if it's that light it should be okay.

FWIW, I buff my glass all the time, cleans up real good.

How would you suggest getting some OLD primer overspray off of a window?

A clay bar might get some of it.

Razor blade + acetone and steel wool if persistent.  If you use steel wool you need to use compressed air afterwards to get the little fibers off your car or you may end up with a freckled car.

NO no steel. You will scratch it. Prob buff out though. I would use an old wool pad to start. Use #3 polish. (I believe its the 3m Perfect- it line) Im not home to look. Should buff out though, you can be pretty aggressive with glass, its much stiffer than the body panels. With anything, start soft and work your way back to the coarser grit. Work the windshield probably three times getting lighter pressure every time. Then try to remove all your product.. rinsing pads along the way. Just like paint. You could even break out the trizac on some old glass. Hell, your could try rubbing compounds even. I have all new glass so its a maintenance issue. I generally buff it when I buff the car. Also done a few friends cars with great results.

Edit: on the primer issue.. lacquer thinner is about the nastiest stuff I would use. Let it sit. Use a lot of fresh razor blades if you do, even with the thinner.

I agree to the "no steel wool"

I tried that on mine...now it's all scratched up where I rubbed it with the wool....right in my line of sight as well....

which is why I was asking on how to take these out without replacing the windshield

I looked at some of it. The reviews are hit or miss...You really need to start fine to medium and then harsh abrasives.. Its a brave man who walks up to a windshield with a drill.. Practice on some old glass first. You wont be sorry.

I ended up ordering a kit off of Amazon which appears to be the exact same kit only $10 less.

Based on the ratings and comments of the kit- it works very well.  Thanks for sharing!  Will be picking up a kit!
