Works on mirrors as well.

July 14, 2021

I used this product on a large 3 x 8 foot bathroom mirror that had a 4 inch crack growing from one of the corners. I was really pleased how well this product wicked into the crack and made it almost disappear. I can still see two thin lines which are the front and back of the crack but it is hardly noticeable and the crack has not continued to grow. Since the product needs UV light to cure, I had to buy a $12 UV flashlight to cure it to avoid having to drag such a larger mirror outside.

This repair kit works great! Get to the craack ASAP and your windshield won't crack any further. My husband keeps 2 on hand at all times. I ordered them on WM.COM because we can hardly find them in the store. They came quickly and saved us a lot of time and trouble running around.

Takes time to work but good product

Great product.

June 23, 2021

I tried this after reviewing the YouTube videos on the product. It does a great job. I had 4 rock chips and part of the result depends on the type and size of the chip. One chip was like a bullseye that repaired very good but not perfect. The other chips had some of the surface of the glass knocked out. Those had just a rough look in the area where the surface was gone, a little larger than the head of a pin. But the cracks filled in and disappeared. This product was easy to use, follow the directions. I found the best results for me was to repeat steps 4 and 5 a couple of times to get the resin completely in the crack. I would recommend this product.

Glue had leaked out, doesn't repair the crack either

June 12, 2021

When I opened the package, I smelt a strong odor, grabbed the glue and noticed it had leaked out of the small container. Almost half of the content was gone. As you can see in the picture, the blue color printed material on the container had dissolved due to the leakage. Had to wash then wipe my hands multiple times to get rid of the smell. Called Amazon and reported the issue with the leakage. Waiting for a response from the merchant. The leakage of the glue out of the container is the manufacturer's issue not the merchant’s.Applied the remaining glue on the relatively small and simple crack based on the provided instructions, but it didn’t work. Reapplied, but didn't see any results. The entire crack which is not too long in length is still visible. Anyways, lost my money and went through the hassle of ordering, applying the glue and didn't see a result. Not happy.

difficult not easy unless you have seen it done

June 10, 2021

difficult to use and get correct. better to practice on a chipped glass not your wind screen.Use a professional, likely free of charge.The leaking resin dries on the wind screen making a blemish you can'tremove!

Works okay, confusing packaging and directions

June 02, 2021

I purchased this after being surprised with a rock chip in my windshield. I set it up, however the directions were a little confusing, and I ended up spilling a lot of the resin because of the confusing directions and packaging. I was still able to use a little bit of it, however even with the small amount i used, it covered up the crack pretty well. I'm sure it would fully cover the chip if I had used it properly, however, again, 1 star off for confusing packaging and directions.

Works like magic!

May 26, 2021

unbelievable! I got hit with a rock and by the time I got home the crack was half way down. I ordered this and received it the next day ON SUNDAY! I had reservations but cannot believe how this thing works-right before your eyes! It just saved me $300. I bought these for stocking stuffers for my kids to have in their car, because it is better if you can get to it before it cracks. Amazing! When I called my car repair place, they actually recommended this brand.

It works. It is not perfect.

May 23, 2021

It worksto fix the chip and crack on my windshield. It is not perfect as if i try to look for it from different angle, i would still find it. Disappear by 90% i guess. Something to improve, the plastic films should be in a bag instead of folding with the instruction (i drop it all over by open the instruction). the pressure tube should be flat. I found an uneven spot on mine so 1 star off.My mistake that you could avoid.Don't apply too much pressure, the crack will get worse if you turn too hard. Check behind the glass as you turn, as long as it not leak and not bubble it should be good.

Worked pretty good, no complaint.

May 23, 2021

A bit difficult to use at first so on my 6" long windshield crack, I didn't make all of the crack disappear but it did seem to seal it up so it has not gotten any longer in the last 4 months. Had it been a bulls eye chip I think It would have worked perfectly. I'll use it again should I get another ding on the windshield.

This stuff can seal and halt a windshield crack!

May 06, 2021

Something fell on my Cadillac windshield (branch?) and caused a small pit and a zigzag crack in the outer layer. I know this stuff is great on bullseyes but a crack? Follow directions and put it on the crack after filling the pit under pressure. It soaked in and almost made it all disappear but at least it stopped spreading. If you didn't know where it was , you can hardly see it. Safelite would have just changed the whole windshield to the tune of $389 plus extras. It is an antenna windshield. Try this before you get hosed by some glass outfit.

TERRIBLE design

April 11, 2021

ABSOLUTELY TERRIBLE DESIGN. I couldn't find one of the old single / double repair kits at the store that uses a disc to seal around the pinhead sized chip in my windshield that had perhaps a 1/4' crack extending from two sides. The RainX 4 cup design holds secure but even with minimal pressure it caused the cracks to spread. Now I have a set of 3/4" cracks and the resin would not begin to fix either. I will go back to the old disc design next time, but for now, I fear it is too late.

It really does work, and you can't beat the price. Its a 10-15 minute process and your cracked windshield is fixed! Though, if it is a deep cracked, I recommend buying 2 of these just to have some for backup and retreat later.

Better then Safelite.

I had read other reviews about this particular product, but was still a little skeptical. It exceeded my expectations. Take your time and follow the included directions and it is amazing!

Flexible option if you have cracks

August 08, 2020

While I am partial to the Permatex type solution for chips, this solution works reasonably well for cracks if you follow the instructions of slowly filling the crack in a continuous motion.
