Dicor Diseal Tape Versus Eternabond Tape

I see in the forums were many say not to use the Dicor Diseal tape and to get Eternabond tape instead. Can anyone tell me why? What is wrong with using Dicor diseal instead. Is it the Eternabond advertisement that makes it better. After all dicor sealer is used almost extensively for sealing around vents and things on the roof. I have a 50 ft roll of DiSeal tape, but don't want to use it if it is going to cause me problems. Would like to hear from users of both products and reason why one is better.

I resealed everything on my roof 1.5 years ago. I used eternabond tape for most areas because I have two RVing friends that had used eternabond over ten years ago. The tape still looked good ..... sold me. I did not know there was another brand at the time. If Dicor makes similar claims to longevity, I would use it if you already have it.

Last summer I asked an Eternabond rep what the difference was between his tape and Dicor's. He confirmed they did not make the tape for Dicor and didn't really know how there's was difference. I use Eternabond for all my repairs.

Two years ago my roof developed a short radius crack. Camping World was near by my location then. They had Dicor Diseal repair kits in stock. They did not have any Eternabond. I used the Dicor tape to cover over and seal the crack. It looks exactly the same today as the day I applied it. When I applied it, I learned that accuracy is paramount. That stuff really sticks, and when it sticks, you can't get it off!

I use Eternabond. The reason I use it is it was recommended by friends who have used it for years. I bought a role of Eternabond 2 years ago, sealed 2 vents, and then sealed the rest. Since I do not know anyone who uses the Dicor brand, I don't want to be the first, and rather stick to the known. It may be better, but someone needs to test it.

Bought a roll of non-eternabond tape a while back to seal the front cap-to-roof seam and other areas. Disappointed to see that the forward edge of the tape had peeled back exposing the joint to rain. Possible my installation error, but the other applications have held up well. I did revert to Dicor self-leveling caulk for the the critical front seam.
