I went cold turky myself (I tend to run that way) It took a few weeks but I got the chin down now. However there is one spot under my chin on the right side, down a couple inches, that really bugs the bejesus out of me. The hairs grow flat and into a hollow, a bugger to get them up. Time will tell. After I fix up the cracked Dwarf's I may try the smallre edges to get that spot... see what happens.
