I have heard of the fantastic adhesion properties of Eternabond and can certainly see it's uses on various parts of the camper. But I am a bit afraid to use it on such areas as vent openings....areas ...
I put it around all my roof vents. I figure I will worry about the removal when I have to. In most areas it will work fine to leave it on and just go over with new product. For now I have peace of mind knowing that I have a great product keeping out the water.
