First let me say wear disposable gloves. This stuff stains hands and clothes. Replaced an exhaust u clamp with a band clamp and had a small leak around band clamp due to one pipe being smaller than the other. Went with this because of the high temp and quick dry time. Applied and waited almost 2hrs and was still tacky and exhaust leak was still there. Oh well It will hold til spring when I replace the resonator. This is why I went with a solution that I could remove in the spring unlike JB weld which is a more permanent fix. Didnt dry in one minute like it claims. Didnt even cure in 2 hrs. Maybe good for other things but not exhaust.

the permatex never dried, after a few days it came off in my hands and was still googey.
