You don't need fiberglass.
The fabrics work a lot better with epoxy.
The wet out is fantastic.
The question a bit hard to answer since people use weights from one ounce up
to six or more.
A lot of builders only use tape on the inside. You can find the synthetics.

Once you use the fabrics you never go back to fiberglass

I am building a S&G canoe. I am going to use fiberglass cloth on the
entire outside for extra strength, and to prevent any checking in the
plywood. I'm useing 1/4" BCx plywood.

What weight of cloth would I want to use for this aplication? And the
next question, how would I decide that on future projects? Is there a
general rule of thumb for weight?

One last question, I know I need to tape the inside and outside with
fiberglass tape on the seams, but If I cover the whole outside with
cloth, do I still need the tape on the outside of the seams?

Thanks,

dave
