I also buy from candle chem , I live about 25 minutes from there..I have only tried 464 wax for a few reasons, shipping prices are so high is one of the reasons ..And for some reason I'm just in love with 464 ..a couple of things that helps me the most with tops is that i pour down my wick, i wrap the jars in felt, i put fat popsicle sticks on top and cover the jars with a box (learned all this on this website) ..so if i make 4 candles 1 might have wet spots but all my tops are smooth..and for a great hot throw if the fo i used doesn't throw that strong at 8% i just move on to another fo ..hope this helps
