You've put my $.02 in the 'right light'. Yes, personally, I wouldn't do it, BUT, as the question was asked, Red can go ahead and paint if he wants. And yes, a 'cheap wood' is preferred. And along with painting the floor, so goes the 'maintenance issue(s)'. The decision IS Red's. I just like the Poster to see 'beyond' the question itself. Perhaps, there are some 'things' that they missed when considering their project. With that in mind, so I speak.
As they say, 'shoot yourself', er ..., 'suit yourself'. ;-)
