Backing Plates for C&C34 Stantions

Make sure that the wooden (balsa or plywood) core beneath the stancheon base is not rotted. If there is rot, simple enlarge the bolt holes, dig out all the rot and inject with polyester mixed with colloidal silica. Try not to use epoxy as a fill, as the thickness of the epoxy might become severely exothermic during the cure, may expand (foam out) and crack the deck.
I use polysulfide as a caulk in ''chamfered'' bolt holes.
