Need to Reseal Front Cap to Roof - What to Use?

Hi, we have a 2007 Winn Voyage with 1-pc fiberglass roof and front fiber glass cap. The cap overlaps the roof so there is a 1/4" offset at the seam. The caulking has deteriorated and I want to scrape original away and reseal. What is the best caulking to use for this location? For the antenna mount and vents I use the Dicor sealant, but it was not used for this location originally and does not seem suitable. Appreciate your help.
Thank you....

We used Eternabond on our several years ago as a preventative. We also did every seam and around any opening up top. Aluminum roof. No leaks.

Comparing the service life of Eternabond to anything that comes out of a tube in a semi liquid state that dries or solidifies I would say forever is an accurate comparison. The bigger the glob the better the job isn't the best method for weather sealing.

Tape it with Eternabond and it's sealed, forever. Caulk it and you'll be resealing in a few years.

In the sealant map above, B is the non-leveling Dicor type goop. D is the one that needs repair. Any one know what the type D Winn sealant is? Or must it be ordered from Winn?

Perhaps call Winnebago customer service and ask what they recommend. Here is a callout sheet that shows the various Winnie sealants for the different applications on your motorhome.

Another vote for Eternabond. I was talked into a couple reseals with Dicor and it will flex and crack on large seams. P

Clean VERY well and use Eternabond.

X2 on the Eternabond tape. I used it on a roof seam on my previous trailer. Applied right it is for all practical purposes a permanent fix. They have full instructions on their website so that you can learn about it in advance before buying it.

My front and rear end caps are sealed to my aluminum roof with Dicor Self-Leveling lap sealant. I had to re-apply last year due to some minor leaks, and after cleaning/applying, the Dicor, no more leaks! I've read many on here that use Eternabond tape for the seams and then the lap sealant along the edges. I think either would do the job nicely for you.
