I've been trying to develop a good potting process for an aerospace application connector. This connector and wire will see -65 F to 450 F and will have to withstand a saltwater immersion that is brought up to 45,000 Ft without a breakdown of internal resistance. So far, no potting will...
Silicone should seal just fine underwater. Try GE. They make the stuff in all sorts of viscosities. How about using a silicone rubber patch with silicone sealant applied to it. Hold it in place with hose clamps.
