[PSUBS-MAILIST] dissolving foam

[Alec Smyth via Personal_Submersibles]

Hi Hank,

I've used both acetone and gasoline for dissolving foam. They worked about
the same, and neither produced something that would pour. I suspect in
either case you'd end up needing a hole large enough to get a hand into the
tank.

Best,
Alec
