We have purchased this unique, hand-split, rough sewn, white pine log siding home. We are concerned about the many gaps, splits between many of the half logs that exposes the tar paper that wraps the house. Is there a caulking or chinking product that can prevent paper deterioration and accept the preservative we will coat the logs with? Should we be overly concerned about these splits, gaps that show the tar paper? Please see the pictures attached. Your recommendation is valued.

You should definitely fill these gaps. If they are on average greater than 3/4” then you should use Perma Chink. If they are on average less than 3/4” you should use Energy Seal caulk. You can get these products from Timeless Wood Care Products at 800-564-2987. DO NOT fill the checks (cracks) in the logs themselves.
