Comments about Permatex Super High Tack Gasket Sealant (1.75 oz):
Great product that works very well. I've previously used small dabs of RTV to keep valve cover gaskets from falling off of covers while reinstalling, but High Tack works much more effectively. It apples easily, gets tacky quickly, and holds gaskets well in place. At the same time, it doesn't dry in such a way that it becomes permanent or difficult to remove.
My tube of High Tack had a tiny pin hole near the bottom that leaked the material any time I tried to use it. I managed to fold the tube from the bottom enough times to sort of stop the leak.
