Leave it alone. 10,000 flying RVs aren't having a problem.
Taken to the extreme, there is such a thing as too much "sealing". Remember, you are also sealing moisture in, which condenses, then evaporates, in a loop. That is much worse for your airframe than if you let the air circulate freely.
Just look at the inside of a thermal pane window with a broken seal. The water isn't friendly, not even to glass.
