Someone school me on UV dried epoxy finishes. I bought a bottle of Lisa Pavelka Magic-Glos, meant for making jewelry, at Michael's Hobby shop, but it does not harden under my Ebay UV flashlight. It will harden if I put it out in the direct sunlight, so I know it works.

My question is: Did I get the wrong epoxy or the wrong flashlight. On my fixed income I can not afford the items sold at the fly shops.
