Eternabond is removable. Takes deliberate effort, but definitely removable. I once helped a friend remove some poorly applied Eternabond from his trailer.
I cover every seam on every RV I've owned (4 now) with no water intrusions so far, in 18 years. I use the 4" stuff and don't think the cost is unreasonable. Dicor has its place, but Eternabond is for the long run.
