cool trick. ive read it in the mags and ive tried it. got a nut, bolt, or almost any threaded thing thats rusted in place? try a candle. heat the thing that you are trying to remove with a propane torch. just like you would with ocy-accetaline but not as hot. melt the candle on the spot heated and let it sit. once it cools it should come right apart. if its too hot the wax burns or smokes. so it might take a couple tries. the wax is thinner than oil and will seap into the threads and becomes the lube.
