Must have in your tool chest
Works great on cars and tractors. Just used it with a new thermostat on my 60 year old tractor. No leaks, easy to apply and cleanup. Seals dry.

Small Tube - Enough for one time use, maybe two
This tube is relatively small. Other reviews said the same thing, but you have to see it for yourself. It's enough to do one housing, maybe two.

Does the job when gaskets/seals can’t.
I’ve use this product twice now on two separate engines after the water pump seal, the expensive rubber / metal gasket/seal, failed to seal. No idea why as they were the top of the line high quality seals with a brand new water pump brand, and all surfaces cleaned beforehand, but they didn’t work. So I turned to this Permatex product and it worked flawlessly on both water pump installations.

You'll need this.
Haven't used yet, but will be needed when I change the thermostat.
