I am experimenting with that now. I have been putting 1/4 oz pp, it has helped reduce frosting and smoother tops. But after burning, the tops still mottle some, I still have a frost burn line (not as bad though), and I do not notice a better hot throw. I dunno, still working with it. I've also got a candle waiting to burn w/ 14oz soy, 2 oz paraffin and 1/4 oz BW - I don't know if I'm wasting my time on that I'm not quite ready to give up and go dyeless.
