I'm planning on finishing my garage walls with OSB. I would like the ability to mount things anywhere (anything heavy will still get a stud) and I really don't feel like taping and mudding an entire garage. Will OSB hold up to the elements? Is there a way I can hide the seams? I'm not opposed to just leaving it as is, but if there's an easy way to smooth it out that'd be nice. Mostly want to make sure it doesn't need a cost of something to keep it from deteriorating.
