Trivia ... RTV stands for room temperature vulcanizing. It "dries" (cures) 
by absorbing moisture. 
To speed the "drying" in a dry environment, cover with a wet paper towel, 
cloth, etc. 

If it smells like acetic acid, it's corrosive. 

If it smells like BenGay (SP?) back rub it's not. Dow Corning 3140 is non 
corrosive. 

NAPA blue gasket compound is a very strong RTV, but is corrosive. The four 
large solar panels on our RV's 
roof are held on place with (only) RTV.
