I just did a Sea King cast

tank. I used Permatex

Motorseal “ fuel resistant”

I have not tested yet due

to cold weather.

another option I might

Try is JB weld, buy  the big

Good Luck,

Bob, I’ve never heard of the Permatex Motorseal sealer.
I’d probably have to order it online.

It makes you wonder what Mercury used for a sealer back in 1941???
It must have held up pretty well.
I guess Gasoila sealer is pretty good fuel resistance. I used it on a Flambeau
once, but it cost a lot, and doesn’t have a very long shelf life.
