J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Re-coring hull #56

After taking up the floor and vermiculite, the time has come to get into the nitty gritty of glass work and re-coring. Trying to cut back the old, poorly done sump repair I quickly found myself into a spot of damp, rotten core. I think I've found my way all the way around it (in the future I will be more careful with my cutting wheel and get any remaining spots from the outside).

Now I'm thinking about adding the new core and glassing over, is anybody familiar with type of epoxy resin and type of glass used? I've counted what looked like 1 standard layer of glass and 4 of roving, does this seem right? Thanks for any help with this one.
