Forgot to mention that Aviation Permatex is different; it is not silicone
based. It is a thick brown liquid about the color and consistency of brown
molasses. . . in January; very thick and slow flowing. It's brushed on in as
thin a coat as you can get and then I always used it with the regular gaskets,
never in place of gaskets.
It comes in a plastic "jar" and has a brush applicator in the lid.
