Stop in for a cup of coffee
I just finished filling the area pictured with 3M black rope caulk, it is great stuff. It helps to put the package in the fridge for a little while and then I put the strips I would be using in the freezer while I was getting ready to do it. I got a little overzealous and used a little too much lol and when I put the trim back on, there is a little sealant visible that looks messy. Maybe on a really cold day I can carefully trim away a little. But again it is a great product!
