I bought a Lancer that had hull damage. the cradle pad had slowly but surely over a year or so created a 1 foot square crack in the aft/port region. i cut the old laminate out (badly damaged) and using the techniques in Casey's book This Old Boat proceeded to make a form and lay up my 15+ layers of glass. the repair size is approx. 10" high and 19" long now. the glass looks great---my question is: Is there anything else i need to do to this inside or out before it's sealed up? thanks.
