EternaBond RSW-2-50 RoofSeal Sealant Tape, White - 2" x 50'

Used on top of caravan to save going up and resealing it every year. Make sure to order a rubber roller to apply pressure to make it sticks properly. Plenty of videos on youtube if your unsure.

Great product, good price, DHL are a useless delivery company though

I can't recommend this stuff enough. It's the best RV roof sealant I've ever used, and I've been using it for over 18 years. In 2007 I bought an older truck camper that has a metal roof with two full-width seams running laterally across it. About a year after I bought it one or both of those seams started leaking. I read up on possible solutions and somewhere read about Eternabond. It was 18 years ago so I don't even remember where I'd first heard about it. But I bought some, sealed both of those seams, and it has never leaked a drop since. I still have that camper and just used it a couple of weeks ago on a trip to the desert. One night it poured rain. I sat inside, cozy, warm and dry. After EIGHTEEN years!! That's how good this stuff is. The caveat is that you have to follow directions. If you're one of those guys who buys something, installs it and reads the directions later, you probably shouldn't bother with Eternabond. There are things you need to know about it. First, the area where you're laying it down needs to be clean and dry. I scrape off all old sealant first and then go over the entire area where the Eternabond will go with Acetone on a rag. Acetone works great. It gets the area clean and evaporates quickly. Second, don't apply Eternabond unless it's at least 70 degrees outside. It's very sticky, but the colder it is outside the less sticky it is. I believe their instructions say you can apply it in colder weather than that, and below 40F or so they have a primer you can use to make it stick better when it's cold. But I've never used that. I prefer to just apply it when it's warm - as I said, at least 70F. There is a clear plastic layer over the gummy part that you remove as you're laying it down. Once you get it laid down, go over it with a hand-held roller, applying downward pressure over all of it. The pressure activates the bonding process. You can also run it over the top of other Eternabond (like where corners meet) and it will stick great to itself. Finally, run a bead of caulk along the leading edges of it, the edges toward the front of your rig. The reason for this is that over several years and many miles, the high winds hitting it from traveling can start to peel the front of it up. It's an extremely slow process, but if you put that bead of caulk down it will protect the leading edge from the wind and you won't have that problem. Besides using it on that camper, I've also used it on my 5th wheel, as recently as 6 months ago. I used it to hold down a sheet of 22 mil billboard vinyl over the entire roof, all cut to fit over all vents, skylight, etc. This rig is no longer mobile and is used solely as guest quarters these days so I didn't need something as sturdy as rubber roofing. I tore all the degraded EPDM off of it and replaced it with billboard vinyl, all held down by Eternabond. Since then we've had some very heavy rain storms and some significant wind, and it's been perfect. No more leaks, no more trouble. I'm a huge fan of Eternabond.

Be sure you're ready. I used it to seal the roof seams on my sprinter van. Works excellent, once it's stuck down its there for life. Roof no longer leaks.

This tape has been invaluable for me and my RV. A recent storm caused damage to my RV roof, creating a hole. The tape provided an immediate solution, and I have not needed to make any further repairs. Additionally, I experienced hail damage to a roof vent, and the tape effectively sealed the hole and halted the leak. I will ensure to keep this product in my RV alongside my tools. It is an essential item for anyone with a trailer.
