Glass

I tried this to fix a scratch on a glass table top curing it with a UV light, but it id not work. Perhaps it needs to be a deep crack. The filler comes out of the scratch when removing the excess with a razor blade.

I'm fairly certain I followed the instructions correctly but who knows because this didn't work at all. Tried it on several different cracks with no success.

Used on my rv windows, works ok.

Icicle feel down from a tree and cracked the corner of my windshield - very visible hairline crack around the 2”x2” corner, edge-to-edge. I could even see the refraction change when I pushed onto the cracked corner lightly with my finger. New car, only 350 miles on it. I was hoping to conceal the crack as shown on the ad photos. Filled the crack, taped it and used epoxy-curing UV light as instructed. The crack was less pronounced, but still very visible after the treatment. I repeated the process. Wet material conceals the crack pretty well, but when it polymerizes, it recedes and reveals the refractive lines. I ended up giving up on this kit and using free windshield replacement mandated by the Massachusetts insurance. When the weather improves a bit, I will try this kit again to fill a star crack on another car’s windshield and report back.

The kit comes with a push pin to force open the crack after the liquid is applied. The first few time I neglected to do this, and the crack spread. After finally using the push pin, the crack has not grown.

Yeah I’m not sure if this was user error or what. I tried this in three mirrors and one window pane. The mirrors never dried even after a few days. The sheets just came right off and the liquid still wet underneath.The window was almost the same. But dried a little better but not enough to fully cure the glass and make it look seamless.Overall not a winner

While the instructions were clear and easy to understand, the product did not perform as illustrated. I tried to repair a single 30" vertical crack on the side window of my van. The liquid did not fill the crack. No more than about three inches were repaired. Ran the liquid down the full length of the crack but very little filled as expected.Save your money, this product doesn't work as advertised.

Bought to fill in a hairline crack in my side window. It's been a few weeks and crack has not grown and a lot harder to notice
