Fixed faucet leak in no time. Teflon and pipe dope couldn't get it done. Normal permatex couldn't get it done even after waiting 24h before turning on the water. Applied this and after a few minutes I turned the water on and no leak! Going on 1 month now without a leak.

Great mechanics sealant and the small tubes work better for my jobs. I don’t throw half a big tube away any more.
