EternaBond RoofSeal White 4" x50' MicroSealant UV Stable RV Roof Seal Repair Tape | 35 mil Total Thickness - EB-RW040-50R - One-Step Durable, Waterproof and Airtight Sealant

The roof of my enclosed trailer started leaking. The 12 year old factory sealant used under the trim had finally given up. After removing all the trim I found how poorly the trailer was constructed. They used rivets every 8-9 inches or so which left a lot of the aluminum skin buckled up; and would have been difficult, if not impossible, to seal. I added a couple hundred additional rivets to make everything smooth, then cleaned all the areas that were going to receive the Eternabond tape. Application is straight forward and easy. Be warned, you need to plan ahead, have a helper if you need one, you only get one shot at placing the tape. After you get it down give it a good rolling. It also worked great on the top-to-side 90° transition; just place it on one surface, roll it to adhere it, then fold it over and roll some more. Pro's: Ease of use, durability, adhesion, quality. This will forever be my goto solution for trailer roof leak repairs. Con's: None really. There is a learning curve to using it but if you've got two brain cells to clank together to make a spark you'll be able to figure it out.

Many have used this product to repair tears in their RV rubber roofs, Even on metal. As long as you follow instructions this product is outstanding as far as adhesion and protection for water intrusion. I bought several rolls in 2006 after purchasing a new travel trailer. I bought a quart of acetone to clean the surfaces that I applied the tape. I covered all the perimeter of the travel trailers roof. Generally the rubber is attached via the rain gutter. There are screws every few inches holding the rubber down and the gutter on. Im my mind, these are all potential leak points. As the saying goes, it's not if your RV leaks, but when. I experienced this with a prior RV even after diligent cleaning and caulking of seams. I did all edges and seams on the roof. All roof vents and even used a pieces underneath the crank up antenna. The product has held up outstanding for the 15 years it has been in place. No leaks. Here are some tips/ thoughts about the product and process; Do not over apply the acetone, just wipe the area and let dry. Once you pull the backing off the tape, be careful. The product sticks very very well. Use a J roller to roll the tape down after applying. Once down, you will not get it off easily. My method was to clean the inside of the guttter and the edge of the rubber roof, I applied the product inside the back edge of the gutter, to cover the screws, and then fold over onto the roof. roll it down. I did front and rear seams where metal siding meets rubber roof. I cannot see any of this work from the ground. I cannot think of anything one can do any better to protect roof seams, than using this product. I will do any trailer I may own in the future. It is not inexpensive, but it has done an outstanding job and no seams have loosened, torn, or failed. Very happy with this product.

Purchased 2009 Thomas Blue Bird Bus, was not leak proof when I took ownership. With this tape, it now is! the seams in the roof had multiple leak points where water had slowly worked the panels up, and some black moss in the same. I had tried to apply lap sealant to the trouble spots, but gave up trying to find specific spots, and decided to do all of the seams with this tape. I used 50' by 2" by 4" and by 6" to cover all of the roof seams. The results are, I now no longer have a leaking bus! NorthWest Washington and Oregon had a flood advisory for 5 days this past week. What I would call a *significant* amount of rain came down, and the only water in this bus was a condensation I caused on my own. No streams of water on the floor, no leaking windows, no dribbles from the ceiling, etc (I'm not being metaphorical here) I'm delighted with this purchase. Go slow, use your thumb around tricky surfaces and after about 10 feet, you'll get a natural feel for putting this stuff down. Some mistakes made: I miss understood the plastic backing at first, on the 2" strip and had some issues applying. This is important to pay attention to, because as other's have experienced, this tape does not want to come back up, after going down. Cut the tape holding the spool together, and that tape also holds the backer for the first layer. I'm not entirely thrilled with the aesthetics. If you have a white roof, this stuff is great. Bus has a yellow gradient on the side that stands out, and unfortunately this stuff is not rated for painting, so I will be painting white around it. My fault. If I'd planned ahead, I'd have painted first. Recommend highly.

We purchased this in the fall of 2019. Very expensive RV waterproofing repair tape but worth the price. As almost all other users proclaim, the best product for seam seals and repairs. Comes in a roll with a clear plastic film once removed, sticks very well, very tacky to begin with and then becomes permanent and difficult to remove. We are amateurs but are DIY fans. We had to seal a badly repaired RV roof seam and moulding where previous owner screwed more screws and applied some kind of putty that dried, cracked and disintegrated over the years. We needed a quick, economical fix. Even though this tape is EXPENSIVE, in the big picture it is a quick, cheap solution and solved our problem. The product manufacturer and users recommend using a roller which works if you have a perfect flat surface to work with. Our situation was with screw heads and chunky, bumpy leftovers of the putty used previously. So make sure you clean the surfaces well with a solvent, we went with isopropyl alcohol. Then do a dry run with the tape before removing the clear film. You literally have one shot at this. I removed the film while rolling out the tape and my wife pressed it into position and used her bare hands to apply pressure to the tape. This created best results for us because of the uneven surface. Eternabond has been applied for about 7 months now and no leaks. This tape can be used for multiple applications but be careful, it is easy to make a sticky nightmare with, Definitely recommend this very expensive product.

This stuff worked great. Patched an old camper trailer's roof that was in really bad shape. I will never use a liquid sealer again.

I fixed a tarp top on my patio and it's the only one that make the job.

This is the bomb of tapes. Forget silicone less mess last longer and works better.
