The foam-in-a-can variety is inferior to the two-part stuff Kevin W. is
recommending.  I believe its resistance to water-induced degradation is lesser,
and its porosity is very irregular, tending to make it more open-cell.  The
two-part formulations eventually get wet, also, in my experience, but that's
probably not an issue if the craft is thoroughly dried between weekend
ventures.

I thought I had a link to data sheets for these PU foams, but I can't locate it
right now.  I bet Erik Sprenne has good links, and Dana Dickson, also.
