foam

I just used pour in foam with success on the topaz.  Both in the inclosed area of the bow and now in another area of the transom.  This last area was taking on water through the motor mount bolts.  These I turned around and glassed into place from the inside first.
My gas tank instructions say not to foam in place.  I still find this tempting as there is foam left and a some space to put it.  Brad-Mi.
