Bought some hypalon sealer from West marine
about 3 years ago - worked great BTW. BUT it's leaking again, bought some more West Marine
stuff and while fishing
around for an air valve that got knocked inside one of the chambers, there was solid hardened chunks of the old sealant
from 3 yrs ago.
Proof that it petrifies inside the tube over time.
Walking around Sam's club there was this green slimey looking tire sealant
offered... question is has anyone dared to try something like this?
