CARPRO CeriGlass Glass Polish - 150mL Kit (5oz)

I used this for water spots that wouldn’t come off windows. It worked well.

Don’t believe the negative reviews. This stuff takes TIME and effort.Had some scratches in the drivers door glass on a brand new truck. Some deep enough to slightly catch my fingernail on. But the scratches were everywhere (birds seeing a reflection and just going to town on my window)Used a DA polisher for application. Took about 20 five minute sessions with a lot of pressure (short sessions to keep glass from getting hot). After a few hours the glass looks new.The included scrubby pad would work for water spots and stuff, but never scratches. So, the pad is worthless. Just grab a DA Polisher and expect a few hours of work and your results will be great.

Man, even with DA polisher I couldn’t get this thing off. Will not buy again.

I used this after seeing it on Chicago Auto Pros on Youtube. I decided to buy it and a glass polishing pad from Griot's Garage. Honestly, it worked quite well to remove the spots I simply couldn't remove with clay or any amount of scrubbing. It didn't, however, remove the fine scratches/pits caused by years of debris in the air on the windshield. Ultimately, that will likely have to be replaced, but at $5,000 for a windshield, I'll wait until something catostrophic happens.

This product actually works to remove scratches from car windshield glass.I got a new wiper blade improperly installed and it flew off while I was driving, allowing the metal mechanism that holds the blade to swipe across my front windshield. This left a long scratch in an arc all the way across my windshield.This product has successfully minimized the scratch after about 10 applications and a lot of elbow grease, but it does work with patience and time. I just used the foam-and-wool applicator to buff out the scratches by hand. Using a power buffer could make the process much quicker.Highly recommend!!

Works very well, but lots of effort is involved. Best with a random orbit polisher and the CARPRO Glass Polishing Pad with interface pads.

This product worked great to remove small scratches and hazing on my windshield! Really must use with a polisher to get results. Used with Griots rayon glass pad and a G9 DA polisher and medium high speed. Took a bit of time and pressure, but turned out better than expected. Had to let the product really work in to the point it started to build heat. That’s when the magic happened, but be careful not to get it too hot. Spritz some water occasionally when polishing. It does fling product so keep that in mind and tape off any rubber trim before use.

Bought this to try and get the micro-pits out of my glass after years of sand/salt/road debris. It seemed to have maybe slightly helped with streaks left from the wiper blades, but it absolutely made no difference on the pits. I used a random orbital polisher with a glass polishing pad.
