Anyone any experience of this foam filling thing? Seems to me you'd want to be pretty sure it's the right sort of foam or you've just turned it into a big sponge.
Other than that it looks a reasonably good bet for <2k?
I think they mean they've blocked the flooding hull system off and filled that with foam, great if it stays dry. Will become very heavy with no outlet if it ever started to absorb water. Normally people just block it off, without the foam
