Yes, this is actually an old trick! And you probably don't have to go anywhere or spend any money, you probably have an old candle around. You heat up the nut/bolt with a propane torch (not too hot!) and then press a wax candle to the nut/bolt threads. Sometimes if you are working on a nut/bolt on an exhaust system you can just let engine heat get the parts hot. The wax melts and wicks into the threads. When the wax cools it acts as a very good lube (much better then any spray!) and you can remove the nut without hammering on anything!
An old trick and a good one!
