My neighbor is having a heck of a time finding the T/C No.13 Bore Cleaner... Is there a shortage of this, or does anyone know if it is going to be discontinued? I use my own home'made concoctions so I'm not dependent on it, but he really likes it and can't seem to find anyone who has any in stock... He's tried; Track, Dixie, Cheaper Then Dirt, and the local stores around here. Any information I could pass on to him?
