Put this on a small hole no bigger than 1/4" or gaps about a 1/16" in exhaust gaskets. Can not be used on flexible pipe. Have other items from last year that are holding together without issue. Odd thing, its activated by water. So you clean area, moisten place needing patch, apply with a build up over area, let dry, run engine shortly to cure product, then good to go. For those on a budget, this can buy time on small issues until you can make a full repair.
