A buddy is putting a faux log siding on his cabin and intends to finish it natural color or some light stain. I'd heard that Thompson's water seal is not really good for this, and my own experience with my deck bears this out.
So, the question: What's a good finish for this type of siding? Brands, please.
BTW, this has to withstand the rigors of northern MN woods weather. That means cold. Cold like most people don't ever experience. (Except of course those of us from North Dakota )
