If they are a snug fit I would not seal, otherwise any moisture that got inside there would have a tough time getting out.
JMHO but I agree 100% with this. We had a small leak in our Kitchen faucet recently (copper tube inside split) & noticed it only because I saw water dripping from one of the edges of the corroplast that overlapped the frame. This was a couple hours after we set up so it took a awhile to work it's way down. Other than it not being sealed watertight alerted us to the problem, I'd hate to think what the outcome would have been if the entire underbelly filled up with water! I can imagine water soaking everything or worse the belly dropping down because of the weight on the road. FWIW my previous trailer had some standing water when I dropped the belly to install SeeLevel gauges & the straps holding up the water tank were badly corroded. It was sealed with the black foam all around & penetrations.
