Easy question, I hope. If there are small bubbles along the edge of a rubber roof on a 5th wheel, does that mean it is leaking or that they air bubbles? I have not seen any leaks inside. I am getting ready to recoat the entire roof with new sealant but wanted to make sure I did not have a major issue. When recoating the roof, should those bubbles be stuck with a pin to remove air (if that is what it is) before recoating or what? Any suggestions?
