I would like to add some additional flotation to a new ( to me ) boat that I
purchased. Does anyone know if any of the brands of canister foam ( Great
Stuff or Dow etc. ) are closed cell and could I use them safely without
concern that they will take on water over the years.

Or, for that matter, could I just use blocks of Styrofoam? The application
is "outdoors" ( on the permanent step/trim tab) on the boat. I'm just trying
to give her more flotation at rest.

Thanks, RichG

Here is a link to Eager plastics they make many types of foam and two
part foam mixes just for this pupose, and they were exteamly helpful
to me a novice when it came to this kind of thing and they will sell
sizes very small to very large. http://www.eagerplastics.com/

Thanks for the reference to Eager, but considering that the area I want to
cover is less than two cubic feet...one of the spray or even a block
polystyrene would suffice, if they aren't going to absorb the heck out of
water right away. I've filed away the Eager reference for future use,
though. thanks RichG
