Eternabond is a great improvement over Dicor. With Dicor or any other sealant used on RV roofs you need to inspect several times a year, recommended monthly, and repair/replace if needed. Though you still need to inspect the roof after storms or monthly for punctures and tears. If properly applied EternaBond
is warranted for 10 years. The Eternabond on my TT is on it's eighth year and still looks like new and to answer your question it's a big No, I do not regret it.
