    Great stuff

    I did not buy this product to make gaskets so I cannot address how well it works for that purpose. I bought it to seal the outside seams and small holes in a DIY solder reflow oven I was building. It works superb for my purposes. Regular caulks and sealers are not formulated to withstand the high heat but this stuff is.

    Used on exhaust manifold

    I had a broken manifold stud, smeared this around the flange and it sealed up the leak pretty good. Not a permanent fix.
