Deck glassing

[DJS]

I am replacing a deck and while the underside had no covering and being mindful of weight; I am proposing a layer of glass on the bottom of the deck before fitting and perhaps two layers of 450 chopped strand with polyester resin on the top.

i sandwiched my deck when doing an Atl 21
one layer beneath the deck is not going to add any great weight to the completed rib, where as any water obsortion into the ply will increase weight

Thanks Nugent and was it 450 you used and how many layers did you end up with on the top side.

I will probably do one on the underside and two on top?
