I might try that. I've heard of filling the ceiling cavity of mid/late '70s cabs with foam but had the same concerns. i would like to get something in that space on my cc project without tearing out the ceiling tin. Been following some arguments I mean discussions on boat forums and seems like 1/2 of them think closed cell spray is ok for interior spaces and flotation, and the rest say only the 2-part catalyst expanding-type seals out water. And then there are some old timers who say any foam will eventually collect moisture and doom awaits us all. I'm guessing that the geezers are right, as usual.
