My HF Flux core welder isn't good for much, but it does apply focused heat to a stuck bolt. I had a Thermostat bolt on a car that broke and would not budge. After about a week of failure, I tried to weld a nut onto the stub. My weld gave out, but the bolt came out easily with vice-grips after that.

ATF is one of those secret penetrating oils that can really get you out of trouble at the wrecking yard.
WD 40 works in a pinch, so does power steering oil, but working at home I prefer Kroil or PB Blaster. The WD folks make a penetrating oil, too.
Back in my past, I had Fieros. They were as crummy as everyone has heard. The bolts were Torx drive and were put in using blue loctite. Using an air impact was not advised for obvious reasons, a breaker bar with a cheater got the job done.
