Kroil first, then Acetone/Trans fluid. Also you can heat the nut or bolt and put Paraffin wax on it. The wax creeps into the voids and acts as a lubricant.
LOL!
Ditto the heat! But have never heard of the wax trick though! I really love it when I learn new old school stuff. That's the best nugget I've heard in a while! I don't get too much old school lernin at my age anymore! Thanks!:cheers:
