That looks all nice and all, but there will come a time when you have to replace one of those ventadomes and you will find yourself tearing into your EPDM roof getting that Eternabond off. Then you will have a real mess on your hands as well as a costly repair.
Eternabond is suitable for REPAIRS to damaged EPDM roofing, but it is not an appropriate replacement for a proper self-leveling sealant job.
As a general rule of thumb, you should never cover over screw heads with Eternabond.
My rv dealer's opinion is that Eternabond is not necessarily forever and should it ever need repair or replacement it will be a bear to deal with. Thus he recommends Dicor. I dunno, I'm just telling you what he thinks. I can see what he's saying, but I don't have enough experience to know if it's really something to be concerned about (my roof is just metal, btw).

I disagree. Should I need to replace a vent, I can simply cut the Eternabond at the edge of the vent frame and remove the vent normally, leaving the Eternabond attached to the rubber roof. Once I drop in a new vent and screw it down, new Eternabond is placed over the vent frame overlapping the old Eternabond.

And that's fine if you wish to do it that way. I just don't think I would want multiple layers of anything on my roof. When I replace a vent, or any other accessory on the roof, I want everything underneath to be stripped clean to get a good seal and then I finish it off with Dicor around the edges and over the screw heads, just as the manufacturer does. God forbid, if something happens to the front cap and it needs to be repaired or replaced, it's much easier to remove the screw strip if it is sealed with Dicor versus Eternabond.
I had a unit a few years ago that someone covered that front screw strip with Eternabond. That unit was the driest unit I've ever had. Never leaked a drop. Then the front cap got tagged and needed to be removed and repaired. It ultimately involved an entire new EPDM roof because there was no way to get the screw strip off without tearing into the EPDM.
Don't get me wrong ... I think your roof looks great. It seems like you took a great deal of time and effort to do a perfect job and I'll bet that is one dry motorhome. From a future repair perspective (and there are always future repairs), I'm just not sure I would have done it that way, that's all.
Eternabond is great for fixing tears, etc., but I don't personally use it in place of a proper sealing job.
My question is; did Eternabond begin as a product for fixing tears, etc. and gradually begin to be promoted to do other things?
Some good points have been brought out on both sides.
To my knowledge, it continues to be marketed as a tear and leak repair.
If you prepare the surface correctly, I can't think of a better product than Eternabond. I love the stuff and use it all the time. Personally, I am just careful about where I choose to apply it because I know that eventually, I will have to undo that repair and it is just easier to deal with scraping up Dicor than it is pulling up Eternabond that has a death grip on anything it touches.
I replaced the entire rubber roof last year and I used the Dicor self leveling on all the vents and used the Eternabond tape on the front and back seams. The tape works really good and if you have ever tried to remove it, you would know how well it sticks.

No Just let it set in the sun light and use a hair dryer to heat the Eternabond even more and just peal it right up, Do what you need to do and replace the Eternabond, The rubber roof will stay put, Nice work there. Eternabond can't be beat.
