I have two needs to inject foam. First: My dinghy
has a couple of flotation chambers. It appears that foam blocks are in there with a lot of room around them, either they were originally as they now appear or they were originally larger and shrank. I'd like to fill the voids. Two: I was repairing a ding at the base of my spade rudder
and had to grind through the skin-- this elicited water
weepage, I subsequently drilled a few half inch holes at various points to facilitate drying out and would like to inject foam in those holes. As an aside I understand your rudder
should be neutral buoyancy???or lighter, or heavier?
Can I use that closed cell house contractors foam with the probe on it? I realize there are a couple of versions of it. Should I use a two part foam? Is there a foam that will not be affected by contact with epoxy
