Cofair Quick Roof vs Eternabond?

Called my local RV shop and asked if they had short rolls of Eternabond. Yes. They did. Went in to get it. Was in a hurry. Bought what they gave me and got home with it. Discovered it wasn't Eternabond, but Cofair Quick Roof.

1. Is it equivalent? Have you used both and can give a comparison?

2. Has "eternabond" become a generic name for this sort of product?

I'm a little annoyed that (1) they sold me this without telling me it wasn't Eternabond, and (2) I was in such a hurry that I didn't notice until I got home.

I like the parts guy in this store, and I will continue to do business with them. But I may return this roll unused, since in these days of online shopping I can get the real thing delivered to my door in a day. This Cofair stuff wasn't even any less expensive than Eternabond.

Or am I making a mountain out of a molehill?

The whole key to why Eternabond is so good is in it's microsealant which is trademarked and proprietary so there ARE NO SUBSTITUTES and IMO all others are just WANNABES and run a DISTANCE SECOND to real Eternabond.

I did my entire roof penetrations along with both edges back in March 2008 and now 11+ years later not a single area (except for about 10in on the leading edge of the front cap seam) have come loose and that one area only about 1/4 in of the 4 in width came loose. I also did not use extra caulk along any of the Eternabond edges except for that front cap leading edge after that small area came loose about 4 or 5 years ago. Properly applied Eternabond is a good as it gets IMO .... I would accept NO SUBSTITUTE PERIOD!!!!
