painting the entire interior of it is a good idea to prevent MOLD.. without paint, it could seep into the wood fibers.. I don't remember what months it was in Florida, but it is the time that you get very cool temperatures, but the humidity at night is so bad, that it's unbearable outside, and the moisture just makes everything sweat water, in the day, the sun dries everything up, and is actually much more comfortable, even though the temperature is much higher..:grin:

and just because I like kicking over the can of worms...

nobody mentioned fire rocking over the OSB to satisfy local codes (if any) and to avoid headaches/stress/losses come insurance claim time...
VOE on the insurance dodge...

I've decided to go with 3/8" plywood. I found it to be the best option for me. I'm going to prime and and paint it.

Now for attaching the ply to the studs I've been debating whether to use 2" deck screws or getting the Hitachi NT 65MA4 DA 15g finish nailer. The nailer would be faster than the screws but then would I need a nailer if I'm not going to do base boards, trim, or crown molding work. I already own an 18g brad nailer and a 23g pin nailer. Is there a benefit from having a 15g nail gun in addition to the other two I already own.

Thanks for the advice.

BTW, I'll post pics of the shop build when I get most of it done. I'm taking pics as I go along.

OSB has a smoother and more consistent finished surface, and a painted OSB wall will have a smoother look than a painted plywood wall. Plywood is more moisture-resistant than OSB, and can be a better choice if you live in a humid climate or if your garage is underground and prone to retain moisture and humidity.
