The touch-and-crayon approach is sort of similar. Touch the wax bar on the iron very briefly, then crayon a stroke or two. Repeat, alternating rapidly.OK, first it was a revelation to realize that I apparently do NOT have the messiest garage in the world after all!
Second, crayoning harder waxes is pretty hard. Ha ha.
So......I clamp my heat gun in my second vise and use it to soften the wax. Works great. Uses less wax, and makes scraping easier.
I'd like to know what @Jacques thinks about this.
