I was using the solarez today with the uv light and the brand of the light is led whole salers and could not get a tack free finish. I have never used uv resin so I dont know could it be the product or maybe the light. Take into fact with the light I was using brand new cheap rayovak batteries that were in the house so maybe that could be the culprit. The thick did the best to where it was some what tacky and the thin waslittle tacky and the flexible was just plain out tacky. all were held under the light for 20 + seconds.
