Looks to be a great product. Delivery was prompt


This is a truly useful product. This roll was 4" wide and 50' long. I used about half of it to cover the cables that run between my Direct TV dish and the roof penetration where the cables go inside the RV. I cleaned the surface well and then used a roller to make sure the tape adhered to the roof and cable.


This stuff just works! I put it all along the top of my RV awning, and it is holding up well in Phoenix sun and also rain while traveling. Easy to put on. Prior to finding this I was looking at an expensive repair or replacement for the awning, but now I think this may just be a permanent fix! (The white also blends well with my awning.)


Delivered on time. good quality no problems


Read all the reviews before purchasing learned from others mistakes. This was easy to apply to the seam in the roof of our Dodge Sprinter. Everytime it rained the wall and celing would be soaked. Dry a bone now. Great product.


This stuff is awesome! I used it to seal my horse trailer roof. It is flexible so will move with the trailer, it seals so well, nd it is easy to apply. I definitely recommend this product. We have had a lot of rain in the month since I applied eternabond to my trailer roof, and not a single drop of water has gotten in. Great product!!


I cut pieces of a roll of this to patch holes on the roof of an old mobile home, and it's so easy to use and it sticks better than anything I've ever seen. Once you lay it down then that's where it stays because it is SO adhesive!! I like!! And this is the only brand that is self-priming, so that is a feature that saves time and the expense of using a primer. I do highly advise that you also get the cleaner that Eternabond makes to clean the surface you are seaming or repairing; its called Eternabond EC-1 Etranaclean Spray Cleaner. Mine came as a 14 oz spray can.

The rubber roof I was fixing was rather brown from the dirt it had collected over time. I first scrubbed with a stiff industrial scrub brush and water; this was rather labor intensive, but I knew I would need all the old embedded dirt out in order to have a good lasting adhesion of this repair tape. Scrubbing with brush and water got it a lot better, but not as white as new, and I did not feel that this was good enough. Then I sprayed the Eternabond cleaner on and wiped it around with a terry wash cloth and this did quickly and easily make it white as new. Next, allow the cleaned surface enough time to get good and dry, and then lay this seal tape on and it's that easy. I am also using it to patch some holes on an aluminum RV roof and on the steel sheet skirting around my mobile home. It's handy to have around. If you are using a lot of it on long runs it would make the job easier if you get a roller; Eternabond recommends and markets their own Eternabond EBR-125 2-1/2" Wide 2Lb Steel Roller, which I haven't tried but iit looks like a good one. Some installers recommend a silicone roller which is what I have (MR05200 Everhard Wrist-SaverTM Silicone Rubber Roller)

In my opinion every hardware store should be stocking this Eternabond seam tape, and the cleaner, and when rainy seasons come they could be selling this stuff like hotcakes.


Works very well for intended purpose


Clean and dry entire surface for complete adhesion. Nice white color to match camper roof


This stuff is great! It made sealing our RV roof so much less work. We have a 15 year old 5th Wheel with the original roof. We had a couple of small, slow leaks. Removing the old caulking was a royal pain, but once removed and the surface cleaned EternaBond went right down - and it stuck tight. Very easy to work with - I am so glad we used this instead of caulking. The liquid sealant that we recoated our roof with went on over the Eternabond and stuck with no problems. Thanks for a terrific product!
