If you can avoid it don't use it. I used it on a small leak that I discovered right before we were to head out on vacation. It worked to get us through but, it has since cracked and made a mess. I redid everything yesterday with the real thing, epdm liquid rubber. The flexseal is very quick in an emergency but, if you have the time to run to Camping World or similar place and get some epdm rubber lap seal you can fix it and forget it.
Also, I would use the lap seal even before the eternabond tape for a repair to a rubber roof. What I have found is that in the short run, eternabond works great. But, if you then recover your roof with epdm liquid rubber you'll eventually start seeing cracks around the edge of where you put the tape down. My guess is that the original rubber and the eternabond tape expand and contract at different levels. I would use eternabond tape for significant holes, say an inch or more. For cracks or small tears the lap seal will do the trick. But again, I would avoid the Flexseal except for emergencies. I keep a tube of lap seal on board now. Lap seal will shed water even before it has dried.
