Do you have a torch. I would try the beeswax trick first.[/quote:tyiep4js]

I'm guessing you slightly heat up the bolt, then apply the beeswax and the heat draws the wax into the threads.

There is several other tricks as well.

Get some PB Blaster and liberally start soaking the stuck nut several times a day for a week or so. Place a wrench on the nut and place a little pressure on the wrench and gently tap the side of it as close to the nut as you can get. Between the soaking and the vibration, it should break lose. 

Or take a torch and carefully heat just the nut until its good and hot. Let it cool off until everything is cool to the touch. Reheat it it, let it cool and repeat several times. The repeated expansion and contraction will break the rust loose as well. 

I had the wheel bolts in our 4-150 stuck so bad that the first one we really leaned on snapped. The cast iron hub had too much mass to heat, so we went and heated each bolt head till it was cherry red, then went to the one next to it. Worked clear around the wheel, then let them all cool several hours, then did it again. Done this four or five times. A cheapie air impact spun them right out like they weren't even tight after doing the above heat and cool several times.
