Sometimes the hot wax melts the hot glue and then the wick travels which can get mighty dangerous.
Normally you fill the gap with high temperature silicone sealant. Liquid tape usually can't handle the heat from being that close to the die.
Hmm, okay. This is what I purchased, exhaust manifolds is one of the product applications. Should be okay, right?
Nothing like a test run to find out. If it fails try this instead.

It's leaking from under the under the gas block and around the gas tube. If it's leaking while it's new, it will only leak more over time. High-temp RTV would be a temporary fix. Don't get any in the gas port or inside the gas block. You can remove the gas tube and put some around the tube. Don't get any inside the tube.
I'm curious as to whether the barrel was dimpled for the set screws. Anyways, if the gas block and the barrel are not a good fit, your best bet would be to go with a clamp-on gas block--my preference over set-screw. There are a lot of options at just about every price range.
I would still check to see if there are any other issues with the gas system. Is the gas key staked? Is there any leakage between the gas key and the bolt carrier body? How tight are the gas rings between the bolt and the cylinder wall of the bolt carrier? If they're too tight, it might take some more shooting before they loosen up.

On my Big Green Egg I used a Rutland gasket and adhered it with Permatex ultra copper. This is a popular combination in Big Green Egg land. Many use 3m Super 77 spray adhesive instead of the Permatex.
The BGE is ceramic, not metal, but I don't see any reason why it shouldn't work. As with sticking anything to any surface, the most important thing is that the surface is clean.
