I have two Excal recurves, wax the string about every 40 shots or so, it will smell funny when the string needs wax, spray the trigger and safety w/ "Tri-Flow" a good Teflon lube from Mal-Wart. Don't get my strings reserved as new ones are only 8 or 9 bucks, and I get 200-300 or better outta them. My wheel bow I just got a few months ago and haven't done anything but drive a long ways to a bow monkey to get the string changed. I can do the strings on the recurves in about 10 minutes, most of which is adjusting the brace height. I don't use any rail lube other than what wax the string leaves, as per Excals instuctions. I do use an old leather glove to rub the wax into the serving, heats it all up some from friction. Good luck!!
