It’s Olympic Redwood Naturaltone. It’s been in our shop for a few years and been through freezing temps on several occasions. I tried some on a scrap and it looks great, it’s just that the stain itself (liquid, in the can) has a very slight "clabbered" look to it, like there’s a slight film of something floating on top. Like I said, it’s very minimal and I probably wouldn’t have noticed if I hadn’t been looking closely. So, what does freezing actually DO to stain?
