Restic to the flame

I bought a copy of Dreadball earlier this year mostly to have a sports boardgame that Henry and I could play. (Owen is happy playing non-sports oriented games.) The material used for the Dreadball figures is, what has come to be called, "restic" -- some combination of resin and plastic. It has a reputation of being difficult to prepare for painting. (For a counter experience read How to clean restic.) One piece of advice I read in the comments section of Seeking advice on preparing the minis for play was to flash the flashing with a cigarette lighter's flame. After too many hours of trimming with a knife I decided the give the flame a go. The basic approach is to warm the material enough so that you can smooth out the heavier flashing with your thumb and for the lighter flashing to burn off. And, after a little trial and error, it does work. However, for detailed, thinly molded elements of the figure you still need to just use a knife. Using the flame often ends with stumpy ears and hands. Even with the few errors the figures look fine after priming.
