Hmm, never thought of trying a heat gun on old tape. Good to know.
I bought an old set of KZG irons to pull the heads and sell and then keep the shafts (UST Proforce Tour Weight). Finally got around to reusing the shafts yesterday. Cut the grips off, and the tape below just peeled off so super easy. Just made my day. Thanks to whoever in golfland made that set.
