Shop Grade Plywood

Peter,

In the lumberyard variety Shop carries "Blows:" dents,
crashes or other serious imperfections here or there that
prevent using 100% of the sheet.

I know two places that carry an AB Marine Shop fir. The
flaws are much less serious, mostly too many boat shaped
patches for a fancy freak.
