I don't know about those, but I was referring to syntactic foam in my
original post, which does not have a crush limit (at least as far as the
ocean depths are concerned).

Of course, syntactic foam is not cheap, but if you're talking about shallow
water (anything under 1000 feet), I'm sure any of the epoxy-based fillers
would be fine. I would definitely check with someone who knows, though...
