I did find one caulked only on the top and sides; but it seemed like after shooting it all over the camper he did not feel like going for another tube.
LOL. Thanks. I'll check mine and caulk any gaps, trying to still leave a way to get the lenses off to replace the bulbs.

If Eternabond is not recommended by the roofing manufacturer, then why is FR placing it on the 'higher' end units??? All of the roof seams on my first Rockwood had to be 'recaulked' after four years. It was needed, and the deterioration of the dicor had resulted in a water leak that seeped into one side wall. On our new unit (2011 2304), one of my first tasks was to Eternabond the roof. I'm glad I did - I was quite disappointed in the quality of the workmanship along the sides (wall joints). The unit was new and clean, so no problem. The material was wider than the Dicor'd seams - so it covered everything well and if it doesn't stick to the Dicor, I'm not worried about that a bit. My final inspection before winter storage showed no lifting. I'm certain that putting Eternabond on all of the joints will provide the advertised protection. At a minimum, it has already given me piece of mind.

Some of you may have seen the photos of my roof that I did last fall with Eternabond. I did front and back seams which included a difficult area around the ladder, a skylight, the frig vent, a couple of vent stacks, two roof vents, and all of the tricky areas around the TV/satellite antennas. All of this took me 7-8 hours. I'm pretty meticulous about such things but I don't think I worked particularly slowly. It's just a very tedious job.

I was hoping that starting this thread would bring out the people who have applied Eternabond. Seems like there has been no problems so far, except the one that was admittedly user error.
Everything has it's pro's and con's and it seems that with the Eternabond the pro's out weigh the con's.

As far as the caulking around the lights, I was thinking it should go all the way around. I'll probably contact Prime Time to get their take on that. I do know that there is caulking behind the lights.

Oh yeah, Char n Kath, it was Prime Time who recommended not using Eternabond, not the roofing manufactuer. Whether you agree with Prime Time or not, they do back what they say with a 25 year warranty on the roof. I don't know of any other rv manufactuer that does that.

Well, I must add that I only applied the Eternabond last fall and at the moment my trailer is covered by at least a foot of snow. So only time will tell.

As much as possible I cleaned the roof surface and the tape itself with acetone when it was applied. When it went down it seemed to stick like nothing else I've ever seen. If you screw up and let it flip over onto itself by accident, don't waste will be hopelessly and forever stuck. Trust me.

One thing that's important is that Eternabond WILL NOT STICK to silicone. I read somewhere that a lot of cleaners have silicone in them so I avoided all cleaners and used nothing but water and/or acetone.

Eternabond doesn't stretch well so there is a definite limit to how much it can be "gathered" around odd shapes or even when over-lapping itself. If applying over an irregular surface I recommend smaller pieces that can be built-up shingle fashion. Like I said earlier, it can be tedious.

Three other buddies and I did our trailers with Eternabond approximately 2-years ago after doing a lot of research on the web. We purchased and used Eternaclean to clean the caulking prior to applying the Eternabond. Not to recommend using other than what the manufacturer suggests, we found that cleaning with Simplegreen followed up lastly with Isopropyl Alcohol worked just as well. The adhesion of the Eternabond is incredibly strong. We also purchased the Eternabond tapered application roller which adheres the tape up close to the caulking. With the tape being 4 inches wide, a lot of adhesion is made surrounding the caulking to prevent leaks. The white surface of the Eternabond is said to be UV stabilized as well.

We have not had a problem and feel pretty confident that it will prevent any leaks in our roof. You may check your roof thoroughly each year but on the chance you miss that one hole or crack and it goes by unnoticed for a while you may have an expensive repair on your hands. Would applying Eternabond to trailer roofs be bad for repair shop business? I am sure that roof leaks bring in some good money each year. Replacing roof vents will probably be a very rare or unlikely event that I am willing to risk versus spending a lot of dough on fixing a leaky roof.

We all still go up and clean our roofs each year, inspect our Eternabond tape and rest well knowing that a leaking roof event is now more unlikely to happen.

My recommendation to those looking at Eternabond is to do your research on the web and make your own decision. Outweigh your risks and benefits.

Happy Camping!!!
