Ferr-l-lite works ok for aluminum,but I find it is too brittle for glue-on points for wood arrows and weak.Take a 1/16-27 NPT pipe tap and tap some threads into the points to give them some teeth and then clean them with alcohol.You won't find these taps as most hardware stores,I got mine from a machinist supply house.For hot melt I use a milky white hot melt,like from 3Rivers or I still have some Bohning Stik-tite.This hot melt takes alittle more heat but stays more pliable then ferr-l-lite.And with threads taped into the point and the white type hot melt,I haven't lost any more points.Get a small propane torch,works better then a lighter.I glue on the points and press them hard and cool them down with a wet rag,then clean off excess.
