Two topics on board speaking of breathing, corn and timber. I like to breath as well. I do understand to a point the application of sealers but are they all they are cracked up to be. bmike mentions hype, what is the ultimate goal? I have a deck on my house with no sealers what so ever and it is working on 15 years, cedar and tamarack. I would happily replace it or pieces of it in 5 years in stead of reapplying any numerous coats of sealers with their attached cost and time and then turn around and have to replace pieces on top of it. The same goes for interior, let it breath.
