We are in the process of gutting our 40X30 barn with hayloft. We use it for storage and horses. We are replacing the old oak with new oak, but have had so many differing opinions as to how to treat the exterior. We've been told by old country folks that we don't have to do anything at all. The barn will still be standing in 25-30 years. Others say to paint it, others to use stain, others still, to cover it with metal. Our finances are limited, as well as time. The lumber is rough hewn oak. Do we need to prime it prior to painting or staining? How many coats of primer? Your info links didn't specify. If we just leave it without any type of paint, how long could we reasonable expect the wood to last? The barn's been here for about 25 years, and only some sections are deteriorating. We're really confused and need to know which would be our best option as well as do we do it now or wait until spring when the wood cures? We'd appreciate any help or suggestions. Thanks, Michi141

We have chosen to build onto our existing mobile home. In the main still-tailer part there is the factory-installed wallboard that basically begins to disintegrate if washed to much. Can I paint over this? And if so, what is the best method? Thanks!
