Guys and Girls, I currently use GB 464 wax. I like this wax, but however, I am still having some frosting issues. I use EVO colors in it and that does help some. When the candle sets up, it is beautiful. But I may come back 2 to 3 days later to find frosting. I have seen this USA on a few websites. I thought about buying it, but was wondering if anyone else had any luck with it. Also, I was curious as to the difference between it and regular Univ. Additive. Is it the same thing? Or, are they trying to sell it under a different name? I was trying to be sure they weren't trying to "Blow" smoke up our butts. Any input would be appreciated. I did a "search" to be sure there were any previous threads on this subject about the testing of it, but I didn't find anything helpful. Take care, Beverly S
