<VV> <vv> penetrants

[Spencer Shepard]

A very effective (and "green") penetrant is bees wax. It is used on large 
(up to 8 inch diameter) nuts on studs on steam turbines that have been 
exposed to temperatures up to 1000 degrees for up to 10 years. Heat the nut 
to a couple of hundred degrees and melt the bees wax into the thread. It 
will come out the other side in a fairly short time and allow the nut to be 
turned without damaging the threads. Probably not real practical on a 
Corvair.
