Setting wood core methods?

[hugo]

i see it like this, the boat was made of wood and poly resin, in 1971 it may or may not have had a transom in the past. i dont know for sure, even if it did it lasted at least twenty years! i will maticulosly grind and clean between any new application of glass and resin, i will add enought to make sure it is strong, i will pray! and why? because i already have 20 yrds of glass and 5 gallons of resin. and im not tossing them out. all i wanted to know was if i should add mat between the core and skin or just paste? or both?... thanks
