Question replacing acrylar/parbond

I'm in the process of re-doing all of the seams on an '07 safari 25 ss se where acrylar or parbond is typically used. What's on there now is the original factory stuff. It was applied on the top and sides of many fixtures such as taillights, stove exhaust fan and fresh water inlet door but not the bottom. Was this just an oversight at the factory or is there a reason for this?

leaving the underside 'unsealed' can help in draining of water that gets 'behind' things.. remember, this is not a 'pressure vessel'... it is not capable of holding lots of air pressure like a commercial airliner. As long as the 'unsealed' area is below the cutout in the aluminum, water should drain nicely.

Since this is the fresh water fill door.. it matches my 1999 Excella.. same 'sealant' method.

Peace and Blessings..

The last thing you want to do is trap water against aluminum. It will corrode because it can't evaporate. It is very common to leave the bottom open on fixtures and probably a "best practice".

Thanks Channing and Shelly for the quick response. I kind of suspected that but didn't know for sure.
