I have a 2025 Grand Design Transcend one. There is a small gap in the lap seal on the back near the bathroom. The gap is between the black metal lip that covers the edge of the corrugated metal back and the existing lap seal that is on the rear edge.
I want to touch it up. The touch up would not directly touch the TPO roof.
Question 1 - can I use liquid rubber (the type in a caulking tube) for this repair?
Question 2 - What lap seal brand/material is recommended for direct to TPO use?
