3M 51111610091 Glass Polishing Compound 60150, 1 Liter Capacity, White, Pack of 1

Originally sold an expired bottle but was immediately contacted and was told a replacement would be sent out immediately.

I purchased this glass compound to remove scratches left from a missing wiper blade on my 2016 Audi windshield. after trying 2 different "glass polishes" i said why not give it one more shot, i'm soo glad i did!! I used this compound with my griots garage 6" polisher and meguiars 6" glass polishing pads. at first it looked like it wasn't gonna come out like the other polishes i used before but i was determined to get the scratches out.. i bumped up the speed on the polisher and did numerous cross hatch patterns over the scratches. i then started to see some results.. it took me about 2 hours of polishing but the scratches came out!! I then continued and did the whole windshield.. my windshield looks better now than when i bought the car brand new!! i'll recommend this product to my mother or anyone who asks me or i hear has scratches on glass.. the trick is patience and a good polishing machine and i know the scratches will come out.. i never write reviews on anything i buy but this performed so well i just had to write one.. great job 3M, Great job!!!

Works well, easy go apply. 3M, you can’t go wrong.

I have some windows with very heavy hard water build up on them. Nothing would take that mineral off and several people authoritatively told me that the glass was etched and could never be cleaned. I took this polish and a high-speed automotive buffer and spent several hours polishing and polishing and polishing. This polish returned the glass to near new condition. The glass is slightly frosted at the corners because I couldn't get the buffer all the way to the edges, but I can see through my window again. Just keep in mind that this polish is very gentle because it has to use such a fine grit to not leave the window with a cloudy haze. Without the electric buffer, I think my impression of this product would be completely different.

I was a bit skeptical if this product was going to work for me at first. I had scratches from my windshield wipers that have been there for years, and I just couldn’t seem to get rid of them. I was about to accept that replacing the windshield was my only option, but wanted to give his glass polish a chance since I would prefer keeping my windshield original. From reading the reviews, I knew that I had to prepare myself for about 2-4 hours of polishing to get results. It was time consuming, but I am very happy with the outcome! I still have a little work to do, but it cleared things up amazingly!
