You don't have to use much resin for it. All you have to do is heat it up until it's nice and melted, then it'll smear easily. The first time I did it, I heated up a metal pipe until all of the resin inside was melted, then I stuck the joint inside the pipe and twisted it around. When I pulled it back out, the entire joint was covered in resin. It got us stoned as fuck and smoked forever:sifone:
