I'm using a combo of c-3 and coconut wax that contains soy. the coconut blend is soft so I added c-3 as I seemed to get more consistency with the texture although I find that most of the time I need to do a second pour. Heat gun makes it worse. Manufactures suggest heating to 200 but I found that it was contributing to messy tops, craters. After testing for a verrryyyy long time I have found through much trial and error that heating to 175 , adding fo right away mixing for about 3 min. and then pouring gives me a decent pour 95% of the time. I find I need to do a second pour to level out tops and finish them off. But the tops are almost always dull I am using three sizes of straight sided jars, 4,8 and 16 oz. sizes. I have read that c-3 can be a pain in the you know what, but I like it better than 464. I haven't tested other soy waxes, so I'm unfamiliar with their appearance. Any input would help thanks.
