Review on Versachem 23009-12PK Type-2 Gasket Sealant - 3 oz. | Pack of 12 | High-Quality Sealant for Gaskets & More by Hunter Schneider

Thick, very sticky thing. Ideal for sealing reusable gaskets in the engine area. I've opened my Harley's camera at least half a dozen times. The same pad. No leaks. Stays plastic and sticky forever. Someone has complained that it is advertised as non-hardening and doesn't harden. mmm Yes. That's the whole point. It's like asphalt, but a sticker. You'll need gasoline or maybe WD40 to get it off your hands and anything it's on.
