Has anyone on here ever used Bittercreek North's EZ Parasoy before? I will be making tarts in clamshells and they also said I can make candles with it also. If you have used it, do you have any advice for me because it will be my first time ever making tarts and candles. I read their site and have been looking for personal testimonials on it but haven't really found any yet. Anything I need to know that may have happened negatively when you used it etc?
