Hey fellas, So I have always called a putty I used in the CG to water proof stuff "monkey shit" Its a putty you put around electrical connections or stuffing tubes to avoid water intrusion. It was always there for me to use. I have no Idea what it is actually called. First person to name it or link the product I send 20 bucks to the airbag fund thing RRW runs in their name. Thanks for the ear fellas your all a good group of people and binaries and such.
We used to use Marine Tex A LOT to fair propeller nuts and other underwater stuff. Also great for emergency (and long term as well) hull repairs. Marine Tex link
