Has anyone used/found a use for Sugru?

I don't know about "best", but this might be worth a try:

Mostly I've used a sacrificial socket. The particular sockets I have in mind are on mil-surplus kit where the kit boxes (and sockets) are easy to find, but the wiring harness (and plugs) between them is like hen's teeth. All I've used as release agent is a coating of silicone grease. The battery connectors are done with a jig made of two spare pins in a bit of MDF.

Epoxy is runnier when fresh, so it tends to get everywhere.

For the uses I've made of Sugru - generally involving moulding to shape - hot-melt glue would be entirely unsuitable (and I'm not sure how you could successfully colour it). Personally I think Sugru is wonderful stuff, but it is expensive and the relatively short shelf- life is an issue.

load it with microballoons. Then it doesn't run at all.

"stay hard when cool" doesn't mean "stay hard when hot"!

Fake Sugru can be made with silicone and sodium bicarb. Google for it - it's on 'instructibles'.
