I'm curious what other people's preferences are on the different types of sealant that goes between the logs on a 3-side log cabin. I've seen people use like a weatherstrip type of seal before and also just strips of fiberglass insulation. But I am curious what other people have used and what works best for them. Backer rods? Oakum? Fiberglass? Some type of weatherstripping of some sort? Please include the pros and cons if you know of any? Thanks.
