Anyone know what that is?!
I do not know what it is, but I know a little bit about it. Just used it last week ("Fix-A-Windshield").
Maybe one of the chemists can narrow it down:
It is just a tiny bit thicker than water.
The instructions call it 'resin'.
UV activated.
Contains methacrylates.
I did not have a lot of faith in the kit. The bullseye in my windshield was nearly 1.5" diameter. Not a regular bullseye, this almost looked like someone taped a white paper disk to windshield. Naturally, straight in from of my eyes.
The apparatus (about 3/8" dia) would not cover the whole bullseye, though the stuff worked its way to the edges (after repeating step 4-6, like the instructions said to do if the cracks did not fill).
Looked very very good! So I filled another much smaller smaller bullseye too (did not work very well because it must have dirt in it after ~10 years).
Moved it into direct sunlight for >90 minutes (instructions say fully cured in 5-10 minutes).
Amazing. Could hardly tell where the bullseye was. Except for a very slight distortion, and my fingerprint (my curiousity ruins many projects).
Down the road maybe 1/4 mile, and the center of the bullseye starts to grow back. (damn) After 2 miles on semi-bad road, it gets bigger. It is still exponentially better than it was.
I think a second application will fix most of the regrown area, except it has to be done when the crack is DRY and it will not stop raining. Could be my bullseye still had moisture in it.
Also seeps into cracks semi-reasonably well. Again, the crack in my windshield is ~10 years old and certainly dirty, but it did help.
I think it would work pretty well for a solar panel. Except I paid $11 for the kit, which contained only 0.035oz/1g of resin.
