I was told years ago to never double wrap@Marbles
Two DIY wraps done. Even with the silicone tape on one, they were under really light. One can is two wraps of the carbon felt with vet wrap and some Tessa Tape and weighs .9oz. The second can still has the original silicone wrap, plus two layers of the felt and came in at 1.2oz. Total cost is $20 for the felt (you can do 9 cans double wrapped), $10 for vet wrap, and $7 for silicone wrap, which is probably optional.
