Hi Andrew,

I did this with exhaust nuts on an engine that had been sitting 20 years. They
wouldn't budge before I put the wax on, but afterwards they spun off with one
hand.

My vote: Great Results. The trick is getting the wax to flow where it's needed,
instead of onto your hand. (Note to self: Wear gloves next time!!)

Happy trails,
