a friend of mine was redoing his barn and I got the tin from the roof the some of the barn siding I'll try and get some better pics of anybody wants to see more
That is very cool.

I enjoy it when people reuse old materials to good effect, and that looks great.
I personally have drywall on my walls, Mildew resistant paint and the lower half is grey. It has never been a problem, but then I have installed a lot of drywall and I don't have a problem with taping,
This is the real reason many guys don't like drywall, even though they won't say it. I like smooth walls, and I felt compelled to cover the insulation.
I like plywood over OSB, as OSB smells for years unless you paint it, and it is a dust catcher. I like the idea of the paintable T111 type board, if the price is right.
FWIW, I was never happy with the look of plain white walls in my garage, it looked too sterile, and not at all like a workshop. Painting the lower walls grey really makes the white drywall look go away.
I built my garage based on my budget, skills and personal preference. It isn't a showcase, but most people like it If you build yours the way you want, it will turn out fine, no matter what materials you use, and nobody will complain.
After a certain point, all the choices become inhibiting, and stop you from moving on. I just wanted walls, so I could move the shelving and stuff back in. I never did score any cool barnboard or metal or free materals. But I got my walls up, made them look nice, and now I am on to the next exciting cartoon adventure.
More adventures please.
