What is a proper grit to prepare "A" faced ply (birch if it makes a

I have often wondered if plywood surfaces aren't contaminated with the glues etc
used to manufacture the plywood. If so, I would assume a solvent wash and or
sanding would remove? Anyone have an idea on this?

Also, how about adding say 10% solvent the the first coat of epoxy (either with or
without the cloth) to aid in penetration of the epoxy into the wood.
