I just removed about 12 feet of Dicor, cleaned it and reapplied Dicor. NOT an easy job especially for an old timer like me. Was wondering if anyone has used Eternabond instead of Dicor over roof seams and what the results have been? Does surface prep require removing old Dicor?

I covered all the roof seams and edges on our 1996 Southwind with Eternabond. It's basically a one time application.
I removed any loose Dicor, cleaned the area and applied the Eternabond.
It's not necessary to remove all the Dicor. I did add a little Dicor to fill in a few low spots to make a smooth area for the Eternabond to adhere.
It has been on for several years and I have had no problems with the Eternabond peeling off.

I did Eternabond on both seams and ran a thin line of Dicor down the edge of the edge of the tape. I'm a belt and suspenders kinda guy. I also put pink stuff in the water system and blow that out with air.

I put Eternabond on all roof seams four years ago and have not had to touch it since. Leave the Dicor in place and thoroughly clean the area with acetone prior to using the Eternabond

Nothing wrong with using both. I do in many situations.

It's not a good idea to use Eternabond around skylights or vents where it's really a pain to remove compared to dicor.

It's easy to remove dicor with a heat gun and a plastic putty knife.

How do you folks tell if its Dicor or a similar product.
I've used nothing but Dicor on my '97 31' 10" trailer. The last time I had any issues was in 2008 when the OEM sealant cracked a bit around one side of the skylite. Simply worked it loose with a putty knife and added self leveling Dicor. looks like OEM. The trailer has never leaked.

Eternabond laying around the roof on all the fixtures/roof jacks/etc looks like bandaids which affects resale and has even caused one trailer owner to loose his new trailer roof warranty.
If you go with Eternabond work it down per instructions and add Dicor (or similar brand self leveling sealant) around the edges like the pros and like the jplante4 picture.

Great stuff for its intended use but is not a permenant fix like some say.

The pros at the local RV service center are using Geocel Proflex for everything now, including roof sealing. I used that when I added a solar panel 3 years ago and it's still shiny. Dicor gets gray after a season. I think the Proflex is easier to remove.

Just wondering - Has anyone that answered about using Eternabond for a seam or edges or around any vents or sky lights had a leak or was it put on as a preventative maintenance procedure?
I've not had any leaks, but have used dicor selfleveling around some cracks in the original "goop" around vents etc. They were not leaking just looked like they might.

I put Eternabond around every roof penetration and my skylight about 10 years ago. It is still holding strong and has never leaked a drop.
