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.
