I am getting ready over the weekend to replace some painted plywood cabinet doors in a rental. I've been asked to keep them as slab plywood doors but I will make them full overlay instead of the full inset like they are now. How do I choose plywood that won't warp or twist? I have some of the 11 ply "cabinet grade" plywood left from the BORG that was discussd a few weeks ago but it has developed bows in the two full sheets that are left. I never thought of them as real high quality plywood (they were selling for $20 after all) but I have never gone to buy truly high grade plywood. Is there a standard for non-warping plywood? Is this Baltic Birch?

Also, I read that you should put a 1/4" edge band on plywood doors to give it a finished edge but would this also help keep it from warping?

Thanks for any help and advice.
