Looks interesting.
Are you using it on the inside or outside of a fuel tank seam?
It has a rather quick pot life of half an hour and cure time of two weeks @ room temp 50% humidity.

Surprisingly low price considering General Dynamics has something to do with it. Since it was engineered back in the fifties it's like the patent on aspirin, there cannot be one!

usually outside. but will use it on inside if accessible. the cure time is longer than typically expected but the results are worth it.

set time normally means you get one shot per purchase package. you must stir the mix exactly as required
