I can't imagine why you would need 100% coverage in order to bond the pieces soundly, but you might want to get a couple of scrap pieces and do some testing for your own satisfaction. Try just laying down some 'S' passes on two pieces of board to give minimal bonding (and weight), then maybe a little bit more to give perhaps 50% coverage on a second pair of scraps, then maybe cover most of the joining faces of a third set except for the edges. Let cure and then stick a putty knife in between the pieces and see how readily they pop apart. In any case, the foam board gets sanded to shape and glassed over, so it's not like it's going to have large shear or peeling forces trying to pop the pieces apart. Oscar Zuniga Medford, OR
