Yes, the old hair dryer trick ! It does leave a nice glazing over the strings/cables... not only that, the heat softens the wax and also the material will absorb the wax much more efficiently when heated, being carefull not to over heat them, which is hard to do with just a hair dryer though. I like to use a wax that is silicone based. It really gets in between all the strands and keeps them from binding. Pure silicone grease goes a long way also..Wax the cables/string when the crossbow is uncocked and then cock it (with safety on of course) to get to the areas you couldn't get to before. Alot of folks will tell you not to but I use a hair dryer to melt the wax and I rub it into the string/cables with my fingers. Ive been doing it this way since the 80's and never had a problem.
