To me that would be akin to duct taping my brand new RV, wait till it needs it.

Thread Summary
This AI-generated summary may contain inaccuracies. Please refer to the full thread for complete details.
Members debated whether to proactively apply Eternabond tape to all roof seams on a brand-new camper or wait until factory caulking shows signs of wear. Some RVers advocate for immediate application, citing peace of mind and long-term leak prevention, with several sharing personal success stories of tape lasting over a decade—even in harsh sun. Others caution that premature application could complicate future maintenance, potentially void warranties, or create a mess if the tape eventually...

Eternabond is not Eternal. It is a great product that can solve a lot of problems. Eventually you get too many layers and it is a mess to pull up and replace, though.
My direct experience. In 2008 I replaced the EDPM roof on my trailer. I had a similar thought to the original poster and put Eternabond all over. Now it is 17 years of Southern California sun later, the EDPM is losing it's white layer. The Eternabond is losing the white tape layer and in places I have had added and extra layer or two for leaks, or suspected leaks. There have been some minor lifting of the tape from the roof in areas. Stuff that can and will be patched with some dicor sealant. The last hurrah for this EDPM roof will be a healthy Tropicool silicone coating over everything. It is not going to be pretty, but should do for another decade, then I can start over with a new EDPM sheet. At that time I will pull the plywood off and fix some sagging roof arches, perhaps add a few more in key areas. And most important, get rid of that low spot in front that collects water.
So Eternabond is great stuff, but there does not seem to be a "forever" solution. It can last a long time, but you still need to do regular inspection/maintainance.
