I used a Silka product, both self leveling and lap sealant last year and am very happy with it.

Thanks for the input. I looked into each suggestion and ordered eternabond tape. I will be cleaning off the old sealant as much as I can.
A Country Coach factory mechanic recommended a torch to add heat for removing old sealant.

Torch? As in pressurized flammable gas? Great tool to soldering copper pipe, not so great on the roof of an RV. Too much heat and a lot of material to catch fire. Heating the old sealant will soften it up and make scraping if off easier but use an electric heat gun. A little easier to manage and not hot enough to set the coach on fire.

Sealant, butyl tape and eternabond tape scraped and cleaned with an electric heat gun. About two hours start to finish with a couple of breaks thrown in. Only thing left was retaping with eternabond and for some reason I don't have a final pic.

It would be great if you came back and answered the questions various posters have asked trying to help you and took the time to respond.
How far down did you run the tape, to the drip rail? Reason I ask is mine has body paint on the top edges wrapping onto the roof. Was thinking the white tape might look off.

I used 2” Black eternabond, ran length of seam. I put the tape to the edge of the trough. It was wide enough to be above the roof seam . It’s been awhile ago but I think it overlapped about 3/4”. I then used 4” white to seal front and rear caps. Like mentioned before clean good . I did recaulk caps keeping flat as possible , then covered with the 4”. I found using a wallpaper seam roller worked well ,especially on the 2”! A bit of work but I think well worth it !

The paint on our coach also goes up to the top of the side radius and I too did not want to put white tape over the paint on the end cap seams. For those parts of the seams, I caulked them using clear Geocel ProFlexRV.

I'm about to do a reseal on my 39' Class A-- if I go over any seams with the tape, can I roll right over the tape once its on with a roof sealer to do the whole roof?

I'm not sure what things chemically argue with each other or not. I just bought it, and I'm going to be very thorough on the roof the first time to try and make preventative maintenance easier.
