Seems like a lot of folks are currently using this stuff. But the concern I have is how well does it hold up over time? Has anyone used it long enough do be able to share experience about the long-term durability.
The reason I ask is that my dentist has used something similar to this to do some surface treatment on my teeth. He claimed that it would be permanent, but in fact it really didn't last very long at all. In some cases, the repairs failed in a matter of hours. I understand that the dental version is likely different from the products discussed here, but the fact that they are UV-cured resins causes me to believe that there are similarities.
