Just bought our new TT 2 weeks ago and about to clean roof for the first time and put 303 protectant on it. Wondering if while I am up there I should be putting Eternabond on all the seams for good measure as a preventative before I have a leak and it is brand new?
Has anyone else done this and how has it held up and how long ago did you do it?
Thanks

As much as I like Eternabond, I would probably not do it, because if there was a roof problem they may say it was caused by that. Now after the warranty was over I would seriously consider using it, but thats me. YMMV

I started with nothing and I still have most of it left
I never fail, I just succeed in finding out what doesn't work

Good point. Chances of having a leak the first year are slim but of course it can happen as we know. I think you are right. I will do it this time next year.
"If it ain't broke, don't fix it." would seem to work here..

I am in the other camp....First thing we did to our new 5th wheel is to install eternabond on the roof. Wanted to install while the Dicor was still in great shape. Made for a nice clean install right over the new Dicor. I did think about the possible warranty implications and decided the risk was out weighed by the long term benefits. YMMV
You can put Eternabond on the seams any time you wish, but wait till the RV manufacturers warranty is done (usually a year). As said, sometimes the RV Manufactuers get testy during the warranty period about what they consider modifications.
You can put 303 on the membrane roof...it wouldn't hurt anything. But it is not recommended by the companies that manufacture the roofing material such as Dicor.
As a matter of fact, they don't like the use of any coatings.
It's simply not needed, as the roof is already protected from UV/Sun Damage.
The white layer on top of the black membrane IS the UV protectant, and it is made to sacrifice itself and "slough off" to protect the roofing material. Thats what the "white streaks" or "black streaks" you see on the side of your RV after a rain are.
You can keep the roof clean, but you don't have to be fanatic about it like some seem to like to do. It's not a hospital operating room floor after all!

I say yes to Etetnabon and no to using any chemicals on the roof other than a mild detergent. The roof membrane is made for long term exposure to sun and elements with uv protection built in. I recently installed eternabond on the front and rear roof seams and it came out great.

My thought is this.
1. The extra UV protectant will help keep the coated UV on longer.
2. Less buildup of the minerals on the roof will keep the black streaks down and less cleaning needed.
I did mine when it was about a week old, the roof was nice and clean and the dicor was clean, I did every opening I could find, even around the antenna, I also changed all the sewer caps and put the cyclone vents on, it took me a few days to do the job but we have never had any kind of a water and with my luck I was pretty sure I was going to get one....one of the main reasons I did mine was because of the ladder, the ladder on the roof wes real close to the seam where the rear cap and the rubber roof met, I was afraid that the dicor seal would break when you stepped that close the seam, so I covered everything I can tell you that is worth every penney, and easier to fix it before you get a water problem...
