My favorite way to smoke resin is by just taking out your slide from your bong and lighting the stem until you see smoke come from the bowl, then put the slide back ont he bong very quikly and then light the bowl again. Resin tastes like shit, but in time of need, its worth it.

If you scrape resin off of a bowl or something a rasor blade works nicely, by lightley scrapping off the res, also it helps if you put a flame on the resin for a bit and then scrape it off, it makes it easier some how.
