Dave,
I'm sure there are scams in every industry ... This would be no different. Just like Corvette restoration, you need to do your homework and get good recommendations from people with experience (that leaves me out
).
Couple notes from surfing this topic:
1)
http://www.300below.com has a neat quote:
"No. Cryogenically Treated parts are never used in my racing team ...Would I lie?"
"And if you believe that, I have an unrestored, one-owner, fuel-injected '63 Corvette split-window with only 500 miles. The point I am trying to make is, major motorsports teams ARE using cryogenics, but there's no way they will give away their secret. "
2) This text from another site will lead me to answer your second question:
"CryoTweaks utilizes a computer controlled process that brings the temperature down to cryogenic levels slowly, minimizing the chance of damage to your items. Once at cryogenic levels, the process maintains the temperature for several hours, then slowly brings the temperature back up. This process is controlled within 1 degree at all times, and it takes several days to complete.
What happens during this process is relatively simple. When metallic objects are frozen, they contract. When they are cryogenically frozen they contract to such a degree that the molecules are fundamenally restructured, i.e. boundaries of the crystal structure of the metal are reduced, if not eliminated. "
3) So, to answer your question about your own deep freezer:
Your parts will absolutely last much longer with this technique ... The longer they are in your freezer, the less use they will get!
Ciao,
Jack
