Caulking Roof to gutter

I'm replacing the caulking on my roof where it meets the gutter on my 2003 Itasca Sunova 30B. The roof is fiberglass and the gutter is aluminum. Removing the old calk is a pain. I'm using picks, razor blades and scotchbright pads. I'm going to need to re-caulk. What should I use? Also why wouldn't I use some Eturnabond (spelling???) tape over it as well after I caulk it? Any reason not to? I never want to do this again!!!

  • Winnebago uses caulk called "Manus Bond". You can get it from Winne, Or the proper caulk from a Winne dealer. It is not at all like Dicor. I do think a 2" wide strip installed over this seam keeps the UV light off this seam and greatly prolongs it's life. It does, however, make working on it a lot more difficult in the future, if ever necessary. There are seams at the front and rear of the roof panel that are caulked with this same "Manus Bond" and can be serviced in the same way.

    Good Luck-- Mick
  • Caulk should last almost forever when covered by Eternabond tape.

    It's not necessary to remove all the old caulk. Just get the loose stuff, clean well and apply the new caulk. Dicor self leveling works great on the horizontal areas, like you are planning.
    Use a hair dryer or heat gun (on low) with a plastic scraper to remove the old caulk.

    After you recaulk, I would apply a strip of Eternabond. Clean well before applying the Eternabond and use a roller. I like a steel roller, some like a wood roller.
    Which ever one you chose, press hard and get a good contact. The Eternabond will last a long time.


    Caulk under the Eternabond is what I use on our 96 Southwind. I think it's a good idea.
    I messed this post up. :S
