Loctite Freeze and Release in an aerosol can:

"Loctite® Freeze & Release instantly freezes seized and rusted parts (bolts, nuts, studs) down to -45ºF (-43°C). The exceptional shock-freeze effect causes microscopic cracks in the layer of rust, allowing the lubricating ingredient to wick directly into the rust by capillary action. The assembly can be easily dismantled after allowing 1–2 minutes penetration time."

Anybody tried the product? It's about twelve bucks a can here in Oz.

It's great stuff I've used it at work and on my car it's awesome. 

always have used PB Blaster in the past, but definitely picking up a can of the loctite next time i'm in lowe's

OK so how is it different from compressed air ... those buggers also freeze things. The can is best turned upside down and sprayed ... insta freeze, BTW spray your hand and insta burn ...
Cool.
