The other good advice is to go back and forth with bolts if you have trouble with them. It is ok to back up the loosening a bit and spray again if you need to. It helped a bunch on some of the bolts. A thread file is also useful in some cases if you don't have one.

After you heat the fastener place a candle on heated bolt/threads and let the candle wax melt into/onto it.
