The advice to avoid acetic-acid smelling RTV because of corrosion is
passed along from person to person like an urban legend, but like an
urban legend it's just about impossible to find anyone who's actually
seen any corrosion result from its use. (A number of queries I've made
over the years has produced just one, using a very early version of RTV.)

HI Roy,

I have been using a different product for over a decade that works
great - liquid vinyl tape. It does a heck of a job for sealing
water-tight connections and, like RTV, doesn'g get hard and crack.
You can buy it a most hardware stores.

Its easy to use and, like was suggest earlier in this thread, I first
wrap the connection with regular vinyl tape (a single layer) before
appling the liquid compond - its makes for much easier removal when
needed.

I've pretty much switched completely to the Plasti-Dip stuff myself. It
is readily available in at least two colors--red and black--at Lowe's.

I used RTV, both the acetic acid and non-acetic acid varieties through
the years. After a couple of unpleasant corrosion experiences with the
acetic acid type, I began either wrapping connectors with vinyl
electrical tape or spraying with acrylic sealant and then applied the
RTV. Either way works well. I recall seeing cautions that one should
be wary of black RTV in that it could conduct. I don't know whether it
can break down but I've used the clear product.
