  Not only that silicon requires such a high temperature to melt that it
is dangerous and could do serious damage to your case.  Most silicon
furnaces are in the Silicon Valley anyway and I don't want to have to take
my bus there just get some sealant for my case. Silicone is cheaper and 
only smells funny.  However I believe the sealant they are talking about 
is something called "Aviation Forma-a-Gasket" a thin tacky not very 
impressive light sealant.  I used the stuff everywhere when I re-built my 
2000 cc Pinto engine.  It is great for glueing the gaskets to the metal 
parts and not very intrusive.  It will most likely disapear if used on 
exhaust components.
