EternaBond RoofSeal Gray 2" x50' MicroSealant UV Stable Seam Repair Tape | 35 mil Total Thickness EB-RG020-50R - One-Step Durable, Waterproof and Airtight Repair

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.

If you have an RV or Boat you need tis in your tool kit

Love this tape. The black tape is another brand I put on after a tire blew out and damaged my camper. It started peeling back and I bought eternabond and put it on today. Amazing! 1st, looks amazing. 2nd, sticks great to the camper. 3rd, I'm not worried now about driving my camper 12 hours and the tape not sticking.

Una vez instalado, adiós goteras, Increíble. Había intentado con otros productos y nada. Esperemos al año entrante porque si sirve para varios años estará súper, de lo contrario, sería una solución cara para un año nada más. Esperaré 2nd year... Excelente!!!

Used this tape to reinforce a 20’ long RV awning that had a few leaks along the top connection seam.
