I just had a new roof put on my old barn, so I'd kinda like to make it look decent again. It was red once upon a time, still is a little I guess but it's pretty weathered. I'm wondering if its possible to paint or stain it at this point and have it stick? I'd hate to paint it and then have it peel in short order, looking even worse than it does now. How would you go about prepping to help it stick, and which products would you recommend?
