Hi John,

I like polyurethanes for this sort of thing.  They are substantially
stronger than RTV, and if you need to re-do it, you won't be left with
that oily texture that nothing else will stick to.  "3M Marine
Adhesive Sealant Fast Cure 4000 UV" might be a good choice, and
Sikaflex also makes some really good options.  One downside is that
even the "fast cure" polyurethanes cure rather slowly.

If you go with RTV, look for a "neutral cure" type.  Others typically
off-gas acetic acid when they cure, which can corrode wiring.

Good luck,

Alex MeVay
