We bought out 1999 Itasca Suncruiser in Dec of 2004 and picked it up in January of 2005. After reading of the problems with the roof edge seal I checked and the entire length was loose. So I cleaned it and applied 3M 4200 hoping to get a good seal with some flexibility. Wrong, after a 600 mile trip I just got around to checking the roof seal and it was all loose again. So now I am in the process if appling eternabond tape and hope that this will finally fix it. Aparently 3M 4200 does not like the metal channel because it stuck good to the fiberglass but broke away from the metal channel.

It is amazing that the last two posts relate to this "roof problem." I had just posted my "to sell or not to sell" when I read your post. I have had the last two seals done by my dealer. They check it every year and reseal when necessary. I have had no problems with their work. It just doesn't last more than an year +. It is just what happened to you that makes me have the people in the know do.
Eterna bond is something I would consider and if it worked well I would keep our 01, because we really like it. My problem with Eterna bond, and no one has addressed this, is the high profile that it becomes after it is aplied. We live in a wet climite and the extra edge that Eterna bond would have would create a water flow problem and algae would begin to grow in the upward edge. I have enough algae as it is without creating more. Thank heavens for tooth brushes. Good luck on your solution.

My exact same problem after only a few hundred miles it was coming loose again in places after caulking. Many folks don't know they have to press on the roof at the seam to tell if the bond is broken. For me the only way to fix the problem is with Eternabond. Again prep is the key to good bond. The poster thinking the extra edge might be a place for algae growth. I suppose to a point if you live in a very wet or humid area you most likely will get a little algae along the tape to roof edge. But my thinking is if you have that much problem with algae you must have to wash the roof frequently anyway. Like any thing if you clean it before it gets out of hand it's easier to clean. I use a car wash and wax on the roof and it cleans up very easy each time. I clean the roof about twice a year. Yours you might do monthly if you have that much algae problem. It only takes about 20 minutes to give the roof a good scrubbing. I believe you will find the 20 minutes spend cleaning is better than the time needed to clean off old caulk and redo.

The "problem" with 3M 4200 not holding is that the roof and J-channel have to be meticulously clean and free of any wax or trace of silicone. This will require a lot more effore than just washing or wiping with a damp rag. If this isn't done, 4200, 5200, or Manis-Bond (the stuff originally used and very much like 4200), will not adhere.

That's just great, I just did my roof seam with the stuff they sell at camping world just for roofs. I cleaned the seam after scraping out the old caulk with brake clean. The dealer did this just 18 monthsa ago and the whole seal failed. I don't mind paying the 500.00 or so to do the job but I think that I can do a much better job for about 40.00 and a couple of hours time. We'll see, time will tell.

Well got the etherbond on, so lets hope it is everything it is supposed to be. It took about 3 hours with cleaning with acetone and sticking it on. I did waste about 3 feet initially till I figured out how to do it, duh. One question what is the best way to get the glue off that oozes out in places? I do not want to mess it up by using something that wull disolve the tape.

I don't understand what oozed out, there is no excess adhesive on the tape to make a mess. Just clean the surface, let it dry, apply the Eterabond and roll with a small roller as you go. Only way to get any mess is if you try moving the tape once it touches. Fill me in on this one.

The edge of the tape has excess adhesive that pulled out as I was unrolling the tape. When I smoothed it down some of it got on the fiberglass nad made black sticky spots. I would like to know how to remove them. Thanks for any info.

Maybe I've been lucky, but have not had the same problem. Sounds like you might have installed the tape when it was very warm. I would think maybe acetone might cut the adhesive, but I really don't know. I suggest you call Eternabond at 1-888-336-2663 and ask them. Please post there suggested clean up.

I called eternabond and they said that acetone would be good for removing the excess adhesive. I think it started when I cut the tape in two. Some of the adhesive pulled out as I cut it and then when I applied it and pushed it down the adhesive spread onto the fiberglass.

Thanks for the update from Eternabond. I understand how cutting it and having it get a little messy could happen. Good luck on the cleanup and I'm thinking when you done you'll be very happy. Especially in years to come and not have to caulk again.

Does Winne have anything to say about using Eternabond? I think they should recomend alternatives to the constant seam maintance. It would be nice to hear from them, but you won't!

The seam is a money maker for the Winne dealers and an easy way to get out of roof warranty issues. There not going to tell you a cure all for the seam problem. I have talked to roofers that have used the stuff for several years. It's great stuff. You have to do what you think is right not wait for Winne to tell you.
