I have a cabin in the woods of VT that is sided with milled pine boards. 2yrs ago I stained it with cabots translucent stain (recommended). This spring the entire house was black. The mildew/mold was behind the stain and I had to strip everything off. AWEFUL. It was a first. What clear product would be best to use that would not turn black? I wish I could post photos so you could see!!! Thanks…
