Eternabond

Yes; Eternabond recommends sealing the edges.

Use EternaCaulk, not Dicor.

Using Eternabond on that new unit may void your trailers roof warranty as one rv.net member found out.

If your trying to fix something the mfg did I would let the dealer fix it under warranty. That way they can't say your attempt created a issue now or down the road.

The tape should lay flat with no raised edges. Then seal the edges to keep water out for a OEM look.

why not use dicor on the edges?

I second the question about dicor?

I used eternabond on the frontcap of my trailer and then sealed the edge with dicor . Works great and see no reason not to use dicor.

If Eternabond is applied correctly the edges will be completely flat along the edges AND are not required to be "sealed". However, if there are wrinkles in the Eternabond and voids between the tape and roof, those may have to be sealed.
Why would the Eternabond tape not be flat along the edges? When installing the tape, just be careful to insure it is FLAT without wrinkles. I installed my Eternabond approximately 8 years ago, flat, without sealing the edges and it is still totally attached, sealed, along the edges, and without voids.

After a few years in the AZ sun, I'm glad I sealed my edges.

BTW, Dicor will seal the edges just fine on a flat surface. However, on a curved surface I recommend using EternaCaulk. Also, EternaCaulk is clear, Dicor is not which may make a difference to some.

I forgot is mineral spirits is the cleaner before the Eternabond is applied on a rubber roof.

Thanks folks......sealing with Dicor it is....or Eternacaulk if I can find it. Just don't want to retape. And I DO tend to fix small stuff myself....my dealer's service dept sucks a fat one.
