Barn/Shop wall material

[Foozle]

I recently built a metal barn that has three major areas: 60'x50' main building and two 30'x30' wings. I'm planning to put a workshop in the 60'x50' area that will be roughly 40'x25'. The workshop will be mostly for woodworking, but probably will have other general use. I'm trying to decide what the best wall material would be. Friends have suggested OSB or plywood, but thought I'd put it out on the site to tap into all the knowledge here.

Also, on the flooring thread I have a discussion about epoxy flooring and am wondering if I need to put the inner walls up for the workshop before I put the epoxy down, or whether it is ok to epoxy everything and then put up walls after -- didn't know if the process of putting up walls and drilling into the flooring would disrupt the epoxy.

Attaching a few pics of the barn.

If you do the floors first and decide to move or remove the walls, you will have only incidental repairs. Wall material is an open subject. Recycled wood would be my first choice over ply. I hate OSB so much I have to walk wide from it at the store.

My ideal wall covering would be 1x12 pine, lightly white washed in an old garage sort of look. LOL, that's a dollar or two or thousand. I used OSB and had planned to paint but even OSB has a warm wood color to it and I hated to cover that up. It does make it easier to hang things on the wall for sure.

3/4" plywood, PT or lifted up 3/4" from concrete floor. Steel above.

I did my 48'x64'(the 1/2 that's finished so far) In galvanized barn steel and couldn't be happier. Yeah it's a little more costly initially, but I will never have to worry about the initial painting, or any upkeep, it reflects light very well, and gives it more of an industrial look (if you're into that).

As a side note, when this pic was taken I only had 100w equivalent cfl's installed in the fixtures. Now with 105w/400w equivalent cfl's it's like day light in there.
