I will add one more comment about 5 minute repairs. It only takes a few seconds to cure a think layer of resin on the surface of glass with a high quality UV light, or even in the sunlight for that matter. However, almost all glass used in windshields today is UV resistant. I don't remember how much UV it blocks right off the top of my head, but we have tested it ourselves and have verified this fact with several windshield manufacturers, and it is significant.

We don't know what kind of light technicians will be using when they cure a repair, so to be safe we recommend 5 minutes, and that is if you are not curing under pressure. If you are curing under pressure, the UV light directly over the pit area is considerably less, regardless of what type of lamp you use, so you should allow even more time.
