Having tried high temperature silicone sealant, I now vote for a wire hanger. The silicone just got too hot to handle. I twist a loop of 20 or 22 gauge wire around another loop of the same, and twist the second loop around the can so the first loop forms a handle. Works fine. 20 to 22 gauge zinc coated wire works OK for a long time. Staneless would be better, but 19 gauge is the only common small size, and it's too big.
