I had a tear in my roof that my RV dealer repaired with Eternabond tape. It looked great when I picked it up. We went camping the same day I picked it up. When I got to the campsite I went up on the roof to check the repair and the roof had pulled apart....the Eternabond tape didn't hold. I took it back to the dealer on the way home and I'm picking it up tomorrow morning. I'm not sure why it pulled apart, but I'll let you know as soon as I find out. I'm not sure if it was an Eternabond issue, or a user error when applying the tape.
