I've used similar products like that with negative results. Using .023 wire, staggered welding, ice packs, still had warpage with sheet metal. I'm not saying tig welding is a cure all for sheet metal but I've read and been told it helps. Anytime you add heat to unsupported sheet metal your going to have warpage, bottom line......

i would use it for holding pieces in place while i tack them. and for insulating larger parts that need all the heat they can get. will it do this ?
