Impossible to use as directed, not that the directions are helpful to begin with.

It will clean up very light shallow scratches. In my particular instance, the glasses had been stepped on and scratched deeply.
The directions say for deeper scratches a second coat may be applied. If you try that, make sure the first coat is completely cured (otherwise you end up with a milky film on the lenses.) And go slowly.
Not sure how deep a scratch this will clean up, but I went out and bought new glasses. it was worth a try and I'll keep the remaining solution for safety glasses and such.
Overall, I'd say the product performs nearly as advertised but it's certainly no miracle repair.

I tried to repair a shallow scratch on sun glasses, and it simply didn't work. I can see the film it deposited on the lens, but the scratch remains and continues to obstruct my vision. It's the trash for both the glasses and the so-called Lens CPR.
