not saying anything is "wrong" with wood,as a core-but-wood needs to be kept dry-water,especially fresh water is the enemy-dry rotting/delamination...
working outside-how do you keep everything dry ?

i read someone recomend polyester based resin-not the best choice for working with glass and wood-polyester resins only provide a surface bond,also,the polyester resins are not waterproof.

i'm just surprised to see no one using divinycell-it's very easy to work with...i work with these products every day-i've replaced enough rotted transoms,decks,stringers,bulkheads-hard tops with a balsa core,to see the damage water intrusion can cause...

the pilot house i build,will be from composite material-bagged-i've worked with enough composites,at my shop,to be a firm believer in the technology...
