Adam's PolishesGlass Sealant 2.0 4oz - Super Concentrated, Easy Application - Water Simply Rolls Off Treated Surfaces - Designed to Bead Water and Keep Glass Clean

Pretty great stuff and fairly easy to apply with a MF applicator sponge (I tried a MF towel as well but the application was sub par due to lack of personal stability). My only suggestion is to double and triple check the perimeter of your glass. I noticed the first few times that I didn't buff very well all the way to the edge and had what looks like an oily slick/smudge (not a big deal).My personal favorite part about this product is using it not on glass though. My bathroom vanity has pewter faucets that end up covered in ugly water spots within minutes of cleaning. Out of curiosity I sprayed I cleaned them, wiped it with 70% IPA, and then coated with Adam's Glass Sealant... No more water marks. Not sure long it'll last, but it's been a few weeks so far.

The product works as advertised, but like many of these products to cover glass the duration that it last is so so. I still believe that Wolfs Glass Sealant is the best product based on duration.

I use Adam's products on all of my cars, this sealer makes the rain run right off the glass. Well worth the price.

this is another great product from adams polishes. its easy to apply and remove just like all of adams ceramic products very user friendly. its the real deal dont try to sniff it because real ceramics have a strong nail polish smell and this one has it. very good product glass does disappear after applying on clean windshield or glass. another hit from adams good job.

This stuff is probably the best I've used across the board as well as durability is impressive. For the price and results. This is the top of this particular area in the automotive glass clarity and sealent.

I put this on my truck I bought brand new as soon as I got it. I’ve had over two months and it only has 2,000 miles and the product is completely gone. It started to dissipate at around 1,500. I have a RainX product on my car that has last for literally four years with no reapplication. Needless to say, I will be applying that to the truck now.

Not as good as griots glass sealant, have to use more than one application, but definitely still works and is cheaper right now for some reason, unsure of longevity.

A smeared mess. Followed instructions explicitly. Let dry 2 mins. Smeared all over and continued to look like oil on a windscreen. After using several cloths, it’s still streaked and oily. Will use carwash soap and wash it down to get it off. Snake oil in a small $15 bottle. Save your money and deal with spots. Fake news!
