Here is a thread about my waxing tool
I also hand dip some Wheels.
I find it best when the wax is not VERY hot. If it is too hot, the wax coating is too think, and danger is high. You end up needing many coats.
I melt the wax until if flows smoothly, and has no "chunks".
If I hand dip, I usually manipulate the wedge or wheel such that when i pull it out, i let the excess flow to a single point. You will have to figure that part out for yourself. If you do it a couple dozen times, you will get what I am trying to say.
