I think I will set up some life testing in the lab and see if I can create a
corrosion problem with the RTV. I will let you all know what I find out.

I bet you will have no problems with it. For years it has been a
standard to avoid the use of the stuff on or near electronic components
and boards but I have never seen any problems associated with it in the
absence of liquid water or very high humidity.

I will admit there are places where the stuff is very handy and useful
but years of seeing it fail in a marine environment has made me very
cautious about where and how I use it. Personally, I do not have a
single tube of the stuff on my boat and it is a fairly large and
complex old girl with a lot of external wiring with all the stuffing
boxes and penetrators that entails.

There are just too many better products available.
