Amen to that!
When they will not break loose, time for the "hot wrench" ox/acc. torches or propane.
It burns paint and weakens the nuts and studs so you must not over do it. Just enough heat to shift the bond of rust on the threads inside. No need to heat red hot. several heat cycles with WD-40 or liquid wrench in between. Then some old motor oil when it starts to move. Caveat:It is possible to do more damage if you are not careful.
Then there is the mini-grinder w/cutoff wheel, drill 1/8 holes in nut, followed by the big chisel and mini-sledge.
I agree with you Dan, once I had done this hard task with rusty nuts, I WILL NEVER PUT NUTS ON DRY AGAIN,ON ANY VEHICLE, EVER!
