However, it is very expensive. Good Finnish larch, which is rot-resistant and survives untreated outdoors, costs a lot of money. Spruce, on the other hand, which is cheap construction timber, must be protected with Consolan or similar.
Seriously? That would drive me crazy. I would feel the need to sand it down with sandpaper and paint it uniformly. But wood was never my thing, I hated it in HTW class.
