when mine ever leak again...or maybe even preemptively before that happens some day, I plan on most likely using rot doctor...or maybe one of the similar products available...a very slow cure epoxee designed to soak into the wood and encapsulate the fibers from within. I don't know, maybe that's no better really, but it seems to me that it probably is....
and I figure I'll probably some day vent that cavity into the bedroom so that it has a chance to breath...(or an alternative I've considered is to fill the cavity entirely by epoxying in a block to completely fill it then covering with a surface mounted fixture)
....I'm still kicking myself for not having them use better surface mount fixtures and eliminating that cavity cut out when they replaced that entire wall under warranty! 
Oh well....so far the overkill caulk and seal job the bodyshop did is showing no signs of leaking... yet... |
They been using butyl tape for 60 years on RV's. In fact, I recently rebuilt a 1963 Aristocrat Lil' Loafer (frame up restoration), and used butyl tape that will last another 50 years.
If something is to be removeable, I use butyl tape (it comes right off if needed), and trims with a toothpick. For permanent seals, I use marine underwater sealant. After a 7 day cure, it will never leak again.
Added some pics of "Loafie" for your perusement
