kachi's masonite (holeless pegboard) option may work for some people. (can't believe I'm agreeing with him on anything  ). It will take paint well and is very cheap. But it won't hold any weight. You need to find a stud to hang something heavy from it. |
Yea, I agree about the OSB and moisture thing.
About tempered hardboard (masonite), I just read that there are five different grades, and one of them doesn't like paint.

In lieu of reinventing the wheel or taking every project as an opportunity to do something a little different, our original poster might be better served finding something already proven in the field.
If he plans to weld or have sawdust everywhere that might cling to trim boards or get stuck in reveals, then these factors shall rule his design solution.
