I’m ready to apply finish [solvent based wipe-on poly] to a built-in shelving cabinet made of maple plywood. Is it necessary to apply finish to the hidden side of this carcase? I know solid wood furniture requires all sides be coated for even moisture control. But is this necessary since plywood is dimensionally stable?
Thanks.

Not necessary.....
I disagree.
Always apply at least one coat of finish on all surfaces of any piece. It's an indication of craftsmanship. Not always absolutely necessary, but a better way. Raw wood attracts and holds dust. Some woods begin to smell in an unattractive way. Finished surfaces are much easier to clean. Yes, occasionally even the backs and undersides of pieces get cleaned.

I'd agree with Rich. It's not really necessary, and I admit that in my business we usually skip it due to time pressure, but if was for my own house I'd put a coat of finish on the "other side" as well.

David,
I agree with Rich, I always leave the backs off and shoot the inside first so I can get the feel of my gun back after the layoff and then shoot the back and the sides and front last to avoid as much blow back as possible. I always finish both side of plywood and hardwood:retards moisture pick up and dust build up. If you are using wipe on poly you could thin it out a little more for ease of application.
Thanks Terry and all of you for your insights. I will do it right and finish both sides.David
Just to be sure, if the "hidden side" is an interior, then you don't want to use an oil based finish, but shift to shellac or a waterborne. Otherwise you can have odor that lingers and lingers.
Steve-
Good point, and I hadn't considered that. The outside of the carcase [hidden side] will be enclosed in a wall cavity. I'll coat it with water-based poly.Thanks for your help.
