Fiberglass cloth

[farmallman]

Looking for some floor repair advice. My boat is a 93 Steiger craft and after cutting the floor and other deteriorating wood out, to replace my tank, its obvious the floor has been glasses over the original glass. The original plywood in the floor is 3/4" . But measures 1" with the additional glass added. I am looking to find out what oz cloth / mat should be used on the bottom side of the new plywood and what size cloth i should use on the top side. Should i use a thick cloth to the edge of the old 1" floor to try and build up the 1/4" and then over lap the older 1" with a chopped mat ? Should i build the stringers up 1/4" with a thicker cloth ? I am using West System epoxy and Douglas Fir 3/4 " plywood.

Thanks

Farmallman, when I was looking at replacing floor on my rebuild, and wanted to know how much glass cloth was actually used in the original lamination as need to replace floor section
someone gave me the advise to take a sample of the rotten floor out of boat, and use gas flame on the fibreglass section which burns away the resin /hardener and you're left with the actually layers of cloth that we used in construction.
I thought it was a joke at first but it does work
unfortunately this only works if you plan on cutting the floor anyways

cheers

The second link below has some good info on glassing a deck. If you haven't thoroughly inspected ALL the wood components in your boat...You Should!!!! Chances R you'll find more wood needing to be replaced and glassed.
