Hi there, I'm new to this forum too, but have used 464 for some time now. From reading this thread you are using GB 464, right not 415 from your friend? I just have to know how you like it. I changed to 464 after my initial kit that I got for a Christmas gift a while ago. I love 464, I have really never had any problems with frosting, in fact, I had to look up what frosting was because I have never experienced it. My pouring area is in my garage so there have been times where my candles cured too fast an with the 464 you will get some imperfections on top. All I do is touch up the top with a hair dryer, actually I just started using a heat gun for candle top corrections AND preheating the containers, really helps. I've only ever had one problem and that was HT with one scent, Pumpkin Pie, from CS and I am testing as to why right now. I can't wait to hear how you make out with your first pour with 464....Bet you love it! Good Luck! Susan
