2015 Palomini 180FB Roof

The front and back of the roof is sealed with a black sticky caulking of some sort that does not do a good job. It is where the rubber roof meets the fiberglass. It is on very thick. It is also around the vents and antenna. I found bubbles in the back interior wall and it took me awhile to realize what they were. The black caulk is very hard to get off. Does anyone have a easy way to get this stuff off?

Sounds like a previous owner used the wrong stuff. Should be Dicor.

2015 Palomini 180FB Roof

I purchased it new. This is how it came from the factory. It is really hard to find information on this particular model.

Pics of this black caulk would be helpful since Dicor usually is white or tan.

Au contraire!

Here's a screenshot of the Dicor web page on their consumer lap-sealant products. The first variety listed is black. The OP's post has a good description of the way it removes.

To the OP: The best way to resolve leaks in this area is to remove as much Dicor is easy. Then clean the surrounding area well and run a 6" strip of Eternabond from across the entire width of the area. Eternabond is also available in black although the white is much more common. After you apply the Eternabond, be sure to roll it out firmly. A wallpaper seam roller is a lot less expensive than the roller the Eternabond company offers--just a couple of bucks at Lowes and it will stand up to the job.

Larry, i did say "usually", not always. Black Dicor is still rarely seen.

I don't believe this black tar like caulk is Dicor. The Dicor I have seen is like rubber. This is like tar and stays somewhat sticky. Leafs and debris stick to it. It is gobbed on pretty thick. There is also a strip of metal across the back just below the roof that may be part of the seal with about 14 screws in it. I contacted the manufacturer and hopefully they will give me some help. If I can get enough old off the Dicor looks like the best solution. Thank you for your post.

Butyl tape?

If it's still sticky and attracts leaves, dirt, and debris, it could be butyl tape:
https://www.amazon.com/Butyl-Black-C.../dp/B01CUBJ4PS

Usually, that's placed between two surfaces, not out in the open. I've had to remove a bunch of it recently (more to come) and I found that it removes best with a really dull putty knife/scraper and judicious use of a heat gun. Get it a little soft, but don't get anything hot enough to damage the roof membrane.

After you get most of it off, scrub the rest off with a rag and mineral spirits. Finish with a wipedown with isopropyl alcohol. (This sounds goofy but it works.)

If it's pretty flat, you could clean it as best you can, and then put the Eternabond over it.

The sealant in Eternabond seeps at the edges and also collects dirt. If it's easily visible, put a thin bead of Dicor along the edges.

It isn't butyl tape. It is a thick kind of ruff texture gummy black tar like sealant around everything on the roof and along the width of the front of the roof and the back. I had to reseal the bathroom vent and getting it off took days. I was afraid to use anything to harsh on the roof. It was suggested I try citrus cleaner but everyone thinks it is a self leveling sealant like Dicor. I used Dicor to seal the vent and it is smooth and rubbery and is not piled up like this stuff. I read using a heat gun helps which sounds promising. Where it is stuck to the roof it is really bonded but in some places it just lifts off easily. It seems I will have to just take the time and get it off. Hopefully heat will help. Thanks for your reply
