Two questions for those who use UV cured Resin.

I have found a resin sold as Lisa Pavelka in the jewelry section of Michaels. It is primarily used to put a gloss on hand made jewelry. The website says after coating the piece, to put it out in the sun or to use their light to cure it. From the video on the website, it appears to be rather thick. Would this resin be useful for heads and scud backs?

Secondly ? would the hand held UV lights sold on Ebay be adequate to cure these resins? There are 9 and 12 LED versions at prices that are much lower than most other sources.
