RVinTexas

We are facing the infamous roof air bubbles. At this point, it's at the front of our RV and the air is stretching it into a larger bubble when we drive down the highway. There are no visible tears to see where the air is entering. I see all these recommendations online about injecting adhesive under the membrane and using a roller to flatten it, but nothing specifies what type of adhesive I would need. Anyone done this that could give me some insight?
