[Shop-talk] RTV Silicone

[David C.]

I have an older (well, maybe only 15 or so years old, so maybe not that 
old) steel Thermos with a flip top spout built into the cap.  The cap 
gasket (assuming there actually is a gasket) leaks.  I was thinking about 
squirting a bead of RTV silicone in the gasket area and letting it set up 
to stop the leak but I seem to recall that RTV may have toxic additives to 
keep mold and mildew from growing on it.

What does the list think?

thanks,
