Will try it.



I remember my dad using stuff like that back when I was just a kid.
Didn't come in a bag though. He had to glass vials with the
components in it. He used it to put flotation foam on each end
of a canoe and also between the rafters on the underside of a raft
we had in a small lake.

Only thing I noticed in the video is that there cannot be any standing
water in the hole. I seem to remember you commenting that there was
water or the water table was very high or something.




The foam stuff is handy. About 1967, friend got a contract with the navy
to raise a sunken barge at Midway or Wake Island, forget which. He had
never used the equipment, but talked to the vendor and got a class. Navy
shipped him and equipment island and the dispenser gun worked under water.
Filled the barge and refloated it.
