I also tried the fiberglass wick, which seemed to make the can easier to hold, but didn't help so much with insulation....then I read this post:

Apparently, little fiberglass fibers can come off on your fingers. If you then wipe your eyes, it could make for an uncomfortable trip...

I had assumed y'all covered over the wick with something once installed. Definitely don't want to breathe the particles or get them in your eyes. I'm amazed I can still see after insulating my house.

I think I'll just stay with my twine for now. Unfortunately, both the hose tape and duct tape are flammable. I assume Gorilla tape would be as well. Maybe electrical tape.

Foam under alum foil tape. It caught fire. Nasty.

Thinned Silicone painted on. 2 coats. It helps but still not good enough. Works fine on the handle though.

Some thermotec header wrap tape I had laying around with alum foil duct tape over that. No added value for boiling. It helped but not too great for holding for a long time and the outer alum tape heats up too much.

What you might want to try is silicone electrical tape. I had forgotten about that. It is fairly thick, is self sealing, IE you wrap it and the edges that overlap seal. They sell it at marine supply houses. Probably a bit heavy.

You could also use a wool yarn or wool thread wrap. Wool should be fire resistant. Never tried it.

A wool glove makes sense considering you will have them in the pack 3 seasons anyway.

Or a pot lifter. I have been thinking about trying to build an SUL lifter out of titanium, but I have to many other things going on.

A real pot lifter is the most convenient. Still got mine from the 70's.

How about wrapping with fiberglas wick, then painting thinned silicone over the wick?

Thats a good idea
