EternaBondRoofSeal Gray 2" x50' MicroSealant UV Stable RV Roof Seal Repair Tape | 35 mil Total Thickness - EB-RG020-50R - One-Step Durable, Waterproof and Airtight Sealant

I bought a used enclosed snowmobile trailer this winter. The roof was covered with snow but looked good from the inside. The first hint of a problem was the first time I washed the trailer. I noticed soap suds and water streaks running down the inside walls. I grabbed my ladder and the problem was evident immediately. The original silicone seam from the manufacturer had developed stress cracks over the course of 10 years. It was a nice wide silicone seal about an 1 1/2 wide and surprisingly thick. The previous owner had tried to reseal some of these areas with clear silicone and in other areas with what appeared to be some sort of epoxy resin. It may have worked for awhile but the end result was a failure. I would have loved to reapply a silicone bead to the seam but there was no way I could match how it came from the factory. I honestly have no idea how they got the bead of silicone to be so uniform and wide. My initial research led me to a product called dicor lap seal. I cleared one side of trailer of silicone with a razor blade initially and a wire brush attached to my drill to clean the rest. I purchased the dicor lap seal specifically because it was self leveling. I was hoping I could apply a wide bead and it would self level enough to approach the width of the original silicone seal. It was apparent after about an hour after the application that it was no where near the width or thickness of the original seal. The lap seal worked well and it was free from leaks on that side of the trailer but I could tell it wasn't going to last that way for long. I needed something wide to bridge the gap between the upright walls of trailer and the roofline. I did some more research and that's when I found this product. I had enough faith in the product after reading some other reviews here and other sites that I removed all the new dicor lap seal with the same process as the silicone removal. I also removed all the other silicone from the trailer roof. I was a little nervous working with a new product that I had such high expectations from. I started with the back of trailer first because it was the shortest side. I started to enroll the tape in about two foot sections and would remove the plastic backer along with it. I applied the tape evenly, first to the top of the upright wall, and the remaining onto the trailer roof. I would press lightly at first to make sure the tape was where I wanted it. I could remove the tape and reapply with great effort if I had to at this time, which I did do several times throughout the entire project. Once I was satisfied with the placement I rolled the tape with the Eternabond 2 pound roller that I had purchased too. This process was quite simple and the bond afterward was impressive to say the least. I tried to pull a section of the tape off after rolling it just to see how well it adhered. The closest example I can think of that you maybe able to relate to is trying to remove a piece of embedded gum from carpet. This stuff sticks end of story! When I got to the end of the roof I took a scissors and cut the tape off evenly. I overlapped the tape on the ends rather than butt them for what I considered a better waterproof seal. It has rained quite a few times with a few thunderstorms in the mix and thus far no leaks whatsoever. The next test will be to see how it fairs over the winter months. I will try to do an update next spring to see if any leaks occur. There is one thing I would have done differently. I should have purchased the 4" wide tape. It wasn't that much more money and it would have given me an extra two inches of waterproof sealing power. I was concerned the 4" tape would be too hard to work with but I would have been fine. I will be keeping this product on hand. I liked working with it that much and I can use it on a variety of things.

I have used this product for a skylight leak approximately 20 yrs ago on Outbanks of NC on a skylight leak. Used 2" wide and still holding perfectly. Currently bought the 1 1/2" width to seal an Anderson Windows 7'11" bottom door panel that had delaminated (4 doors) that face the west and receive the most daytime sun. The width is perfect, actually looks like the door was made using this product in place of a caulked lip in the offset of the panels.

We started adhering this to our trailer and it was going really well until we came to a foot long section that had no adhesive. It stopped. This was upsetting as we had cut our strip and now we needed to stop mid side, cut out the bad part and then start up again. It was very upsetting as we had just enough to finish the job and didn't want another seam mid way. Not saying don't buy this product but be prepared this might be an issue.

I bought this to bandaid failing solder joints on a Terene roof system. Cleaning down to bare metal and installing using the adhesive primer.Sticks like crazy. Seems to be holding up well. Will wipe down with EPDM primer and top coat with elastomeric roof coating.

we bought this because we were at our last nerve trying to get our shipping container house to not leak between the containers. We tried everything. THIS WORKS! its really sticky, and will grab onto itself if you are not careful, but OH MY GOODNESS, it works! NO MORE LEAKS!!! get it. you won't regret it!
