If all else fails, read and follow the instructions.

Seems like a way to keep it 'eterna' instead of 'temporar.'

I've applied Eternabond tape on several coaches, and have never added anything to the edges.I sealed seams on a flat roof at our house that's been there for ~9 years with no leaks or problems at all. The trick to Eternabond or any similar produict including Dicor, is to get the surface prepped properly. On our present coach, I have covered the front and rear cap seals with Eternabond. It has been on there for 4 years and ~40,000 miles with no lifting, peeling, or degradation.

Dicor self leveling lap sealant does not cost much and Eternabond recommends it. I am waiting for warmer weather to do my cap seams with Eternabond and intend to use the Dicor on edges of the tape.

When we got our (new to us) coach, the eternabond around the shower skylight was lifting on the forward edge - the edge towards the front of the coach. There were no leaks yet but I figured it would eventually develop a leak if left alone. I cleaned the area as well as I could and put a bead of Dicor along the edge of the Eternabond all the way around the skylight. It's been 2 years now and everything is still intact up there with no leaks.

I've installed Eternabond on two motorhomes. It was applied on this mh in March of '05. In October, hurricane wilma came right over top of us. Ninety mph winds struck straight onto the front of the mh. Then after the eye passed us, about 110 mph winds hit directly from the rear. Post storm inspection revealed no damaged or lifted edges to the Eternabond. Its been the same with the 60,000 miles the mh has been driven since that time. The stuff just plane sticks if your application surface is cleaned well. I've not done anything to the edges of my tape.
