I have used Permachink Ultra 2 and Lifeline Advance stain to finish my red pine home, which I recently bought. However, the side that gets the most sun and rain is fairly weathered. I can sand it down and then apply the stain but I wonder if would make sense to pre-treat the logs with a penetrating stain, perhaps something like what would be used on a deck. The logs have very small checks in them and it is hard to imagine that the moisture will not get in there. It seems that the Ultra 2 stain is not particularily penetrating. Any recommendations? Will the Permachink Shellguard RTU serve this purpose?
On another note, has anyone had experience with Permachink Mbalm and EWood to treat punky wood? Does it work? Tips?
