The original and still the best
Anachroman•September 27, 2017
This is the original formulation of RTV (Room Temperature Vulcanizing). I used it first in the 1970s to mount marine radio equipment to any type of surface and to seal penetrations in hulls of vessels exposed to high humidity and salt water. It lasts forever and will not get hard and crack - years later it will still have a rubbery consistency. It has a very strong adhesive bond and allows you plenty of time to work with it before forming a skin. The problem with too many 'silicone' caulks and products is they begin to harden almost instantly and the finished product does not look good unless you are a professional who caulks for a living.
Great sealant

The best. Exact stuff we use where I work.
What you need for tough, long-lasting repairs!!

Dow 732 is what you need for any kind of hot tub work. If you have a fitting or opening that is sealed with silicone which has failed, this is the stuff to get. It seals unlike any other adhesive/caulk I've ever used. Very chemical resistant as well. Thumbs up on this one!
Aircraft approved.

We use this in the aerospace industry, that should tell everything needed. Like liquid tough rubber.
