My go to for really stuck **** is heat followed by PB. If you get it hot, pull the heat off it, and start quenching it with PB, it will come right out. When you first quench it, the PB will just cook right off, but there is a specific point when the part is still hot, but cool enough not to burn the PB off, and you can actually see the PB wick into the threads. Hit it a couple more times with the PB until it stops wicking into the threads and you are done. That is when it is time to loosen the bolt.
Try wax, it has a higher flash point. I use beeswax candle stubs left over from my wife's church. I swear they are blessed they work so well!
