Hi Mark, Had the same happen to me on my second boat,first boat was done with 6oz glass it was the first time I ever glassed anything it wet out great and went very well, second boat was glassed with 3.2oz glass and had a bugger of a time wetting it out, the outside was easier to work on BUT inside the hull just like you I could not get rid of the bubbles
and like you I asked this forum what to do and the reply was the same you got.As an after thought I blamed the glass
I thought I bought at a bargain 50yds. at 50in wide for $60.00 it felt a bit more stiff than the 6oz but ignorance is bliss and charged forward,my thought's now are what glass you used and wonder if it is really the glass or more likely me.

I have a bunch of hard-weave 3.2 (?) oz glass as well - it's difficult to wet out even on a flat lamination board.
Another possibility for bubbles is if the temperature in the shop is increasing as the epoxy cures - sometimes out-gassing from the wood (or small cracks & voids) can form bubbles that get trapped behind the semi-cured epoxy and glass. Lots of squeegee work and dropping temperatures are the usual cure.
