How to remove accidental sanding scratches on glass?

[Flapdisk]

Hi Guys, how can I remove marks on door glass where they have been accidentally touched by the DA?

Not an easy task but I know the garages use something like this stuff:

What I don't know is how successful it is.

The last time we used anything to remove scratches in new plate glass toughend door glass about 12mm thick, we used a guy who came out with small sander type machines, various felt bobs and I guess Diamond cutting pastes of various grades, superb job as the glass would have got condemned on a new insatallation. Couldnt see whare he had been polishing when he finished.Gut came from the North East -Newcastle area, so guess not a lot of help.

Maybe dremmel type machines, get some glass, scratch it and practice

as an aside to this (don't want to hijack, but its related) anyone know how to get welding and grinding burn marks out of glass? namely some patio doors that I may have been stood a bit too close too when repairing a bike frame

Oh dear, these tend to be more than a scratch, been there,and got the tea shirt. Mine are in quite deep, but went realy aggresive with G3 and G10 polishing compound, lots a lubrication-water, and presure, got rid of most of the damage and our lass aint noticed, pressure is a problem because of area size and thickness of the glass, and lubrication is a megga MUST, cause you do not want any heat generated into the glass. Again a lot is trial and error, I used to swear by Brasso, buts lots of modern day polishing compounds, even some the "soaps" for polishing metal will cut glass, but heat is a problem so be very very careful

jewelers rouge and a load of elbow grease as long as there not 2 deep . grinding burn marks are a diffrent kettle of fish

will try with the g3, if it works will get some g10 to finish it off

I tried G3 on these marks I have on the glass, didn't do much. After seeing Steve's post I have ordered one of these, there is a demo video on the page.

If you just want to pull the rusty bits out (once they're gone the marks are a lot less noticable), then any of the chelating agents you can spray on will take the spatter/rust marks out with an application or two (I used Bilt hamber AutoWheel when I did the same to the house window whilst being a bit too close welding the frame - but there's probably cheaper commercial stuff out there)

I think it will be a lost cause, there will be that many of them, g3 wont have any effect tried some 3 or 4 years back on a grazed window
