To keep water (or any other corrosive fluid) out.

The Packard Electric guys used to call the stuff "Bear Sh_t".......and it was used to waterproof the connections.

Ha-ha, that's good. At Delco we used to call the clear sticky stuff in some ignition modules sheep snot.

at the time gm didn't have the silicone incerts as they do now in there connectors. so they used black tar to waterproof the connections, which did more harm than good.

Dieletric grease is the best for connectors.

Funny you mention this today. I just wrote something about it in another post. My high speed fan wasnt coming on because there was such a bad connection at the relay from this stuff. I tried different things to clean it out, but what worked best was some ronsonol lighter fluid I had laying around. I tried acetone and carb cleaner, but the lighter fluid with a toothpick and blowgun worked great.
