    I have a few slight (@1/32-1/16") low spots when i put a straight edge on the bottom. Being a racing runabout I know its important to be very flat. Is it permissible to add compound on the lows in just a few areas? Seems like there would still be plenty of bare wood for the ply/epoxy bond.

    I would use thickened epoxy, not fairing compound. Fairing compound may crack and break out under load, I would think you want to use something structural and not cosmetic

    :cool:

    You could used thickened epoxy and let the plywood float when you glue it.

    Scab in a piece of the same species of framing material and plane/hone it down to the desired dimensions.

    Yah...use the same material as the frame for filling substantian gaps.

    If the gap is small high density filler will work fine.

    As Gonzo wrote.

    Or glue thin strips/veneers of wood to the frames, and fair again. I prefer this approach as it is 100% certain to eliminate any chance of a poor glue up.
