As far as sealing elect wires ans stress relief, would hot glue do the trick?

Probably would, but it has a low melting point. My understanding is that there are two types of the stuff, cool-melt and hot-melt, but that they're both pretty low on the scale. Get a hot engine and you could find the stuff has melted and dripped all over the place.

I think the best thing is just to use sealant rated for sealing electrical connections. You can get it from Radio Shack or most supply houses online, it's designed for the task, and it's really not very expensive - one tube lasts a long time. It's basically just silicone caulk but without acetic acid and in squeeze tube form - you could probably just use caulk but who wants to mess with a caulk gun to seal a little connector? =) Besides, what is peace of mind worth to you?

Personally, I'm not so fond of the silicone self-sealing tape. It attracts dirt like a magnet, and my toolbox is never clean. It's also a pain to get around small connectors, although it does a great job for large items. Beware that it's not as heat-resistant as they say it is. One ad for it that I saw had some guy fixing an exhaust tube with it. Yeah, don't try that at home. It gets brittle and cracks when exposed to too much heat. DAMHIKT.
