Facile à utiliser mais attention pas le droit au deuxième essai ### ⭐⭐⭐⭐⭐ Best camper seal tape option ! *by R***A on 27 May 2025* I have used Eternabond Camper Roof Sealant Tape for years to seal my top edges of my slide outs . I recently decided I was going to go over all my dicor on my main roof with Eternabond . I order the 4 inches by 50 feet as part of my pre determined installed plan . I am very impressed with Eternabond as it provides a great seal that will last for years. It is a lot cleaner to apply then lap sealant and can be used as a stand alone seal . The only thing I will say is plan where you are going to stick it in advance as it is very difficult to remove once in place . The key to the tape is applying pressure after it is down where you want it . The roller works great for this . Pre cleaning is also important, I used rubbing alcohol after making sure the area is cleaned with soup and water, then let dry (do not apply if wet, or cold outside). The tape will basically stick and seal to anything other than 100 % silicone! It can be applied right over existing lap sealant as long as you clean it prior. Great to have a roll in your camper incase of an emergency roof repair. Honestly the best place to use this is on your slide roof. Most factory roof installs will have a small two inch layer of Eternabond or other brand of tape. First thing I do is add either a 4” or a 6” wide strip on top of that for added protection . That or both and layer it. Lap sealant cannot be used well on a slide as it will stick to all the seals , so this is definitely the best option . Some tips for install : - cleaning and pressure are keys to a good seal. - mark out where you want to put the tape down prior with a marker so you have some lines to follow . - a window screen seal roller is a helpful tool for applying pressure in tight area . Removal tips : - used a blow dryer or heat gun to gently tear off the top layer of the tape. The top layer will pull off easy, the bottom sealing layer will need to be cleaned up with solvent . If you are reapplying new tape, there is no need to remove the bottom layer. I would recommend any size of Eternabond for repair or an upgraded roof sealant option for a travel trailer . Second time ordering the 4” , second camper I have used it on. ## Frequently Bought Together - ETERNABOND RSW450 - Thetford RV Toilet Seal Lube and Conditioner - Toilet Seal Lubricant - 24 oz 36663 - Valterra T58 Twist-On Waste Valve, Mess-Free Waste Valve for RV's, Campers, Trailers --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/67605954-eternabond-rsw450](https://www.desertcart.ae/products/67605954-eternabond-rsw450) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-07-26*
