MicroSealants are a family of sealants that contain no double bonds between carbon atoms, but are comprised of a single bond between carbon atoms which result in a molecular structure that is extremely stable and is resistant to oxygen, ozone, and heat. MicroSealant tapes are formulated from synthetic polymers and contain a proprietary built-in primer that facilitates instant bonding to most known materials used in: transportation, roofing and the traditional building envelope. MicroSealants have an extremely wide temperature tolerance. When properly installed, MicroSealants will bond to almost any selected substrate, resulting in a waterproof seal. MicroSealants are self-healing. MicroSealants are extremely robust to a wide range of surface condition reducing steps during installation. MicroSealant - contains no solvents due to its completely VOC-free proprietary primer and will not compromise air quality within the building envelope. Why Use EternaBond? EternaBond bonds to virtually any surface except silicone. This includes all roofing materials, brick, wood, metal, stucco, rubber, vinyl, canvas, etc. So EternaBond is the perfect repair product for buildings, RV's, tents, sheds, canoes, tarps, etc. Also, EternaBond has an expected life (depending on where you live) of 18-35 years exposed to the weather. EternaBond has a 5-year shelf life so if you don't use it all at once it will be ready when you need it. Finally, EternaBond is the choice of professional RV mechanics, roofing technicians and professional maintenance mechanics. What makes EternaBond different? EternaBond is a MicroSealant. MicroSealant has a unique molecular structure which makes them extremely stable, almost invisible to the degrading effects of nature, resulting in extremely long repairs and shelf life. This unique structure also makes all EternaBond tapes compatible with almost all other materials except silicone. Review: Worked Fantastically - 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. Review: Great, but within reason. - Works at the transistion points of the roof of a RV well, I wish you could peal the backing off once firmly pressed in place, leaving just the tar substrate. The backing makes it "waterproof" but future leaks around the tape and the issue that the outer coating is slippery. Very little will stick to the outer coating of the tape but does stick very well to the RV surface. Lap sealant will not adhere to the tape covering so if future repairs are required it is a real pain. ## Features - MULTI-USE: Perfect for use on metal buildings, trailer/RV roofs and sides, drain pans, drain pipes, boats, canoes. bonds to a wide range of surfaces including roof materials such as EPDM, TPO, Hypalon, aluminum, galvanized steel, wood, and fiberglass. - NO ADDITIONAL SEALING REQUIRED: Aluminum backing, combined with a layer of advanced MicroSealant, creates a waterproof, moisture, and air tight barrier with no additional sealing required that remains flexible to -57°C (-70°F) - DURABLE SURFACE: Industry leading one step repair system that creates a protective coating for surfaces that require abrasion and corrosion resistance - EXCELLENT UV RESISTANCE: Tape features a durable and UV-stable backing that withstands deterioration in fluctuating temperatures and direct sun exposure - EASY TO USE: Simple and quick one-step repair, using sticky tape with no trays or messy solvents to clean up after the project completion, and no other adhesive needed ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00ER9P4FQ | | Adhesive Format | Tape | | Adhesive Location | One-sided | | Adhesive Side Count | 1 | | Best Sellers Rank | #220,013 in Automotive ( See Top 100 in Automotive ) #562 in RV Cleaning & Maintenance | | Brand | EternaBond | | Brand Name | EternaBond | | Color | Gray | | Compatible Material | Metal, Wood | | Customer Reviews | 4.8 out of 5 stars 14,030 Reviews | | Foil Thickness | 35 Mils | | Item Dimensions L x W x Thickness | 2"W | | Item Resistance | waterproof, moisture resistant | | Item Thickness | 35 Mils | | Item Weight | 1.4 Pounds | | Manufacturer | Eternabond RoofSeal | | Material | Aluminum , Fiberglass, Silicone | | Material Type | Aluminum, Fiberglass, Silicone | | Model | EB-RG020-50 | | Number of Items | 1 | | Other Special Features of the Product | Durable | | Part Number | EB-RG020-50 | | Recommended Uses For Product | Packaging | | Size Name | 2" x 50' | | Special Feature | Durable | | Surface Recommendation | Wood,Metal | | UPC | 891991000458 | | Unit Count | 8 Feet | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** EternaBond - **Color:** Gray - **Material:** Aluminum, Fiberglass, Silicone - **Number of Items:** 1 - **Recommended Uses For Product:** Packaging ## Images ![EternaBond RoofSeal Gray 2" x50' MicroSealant UV Stable RV Roof Seal Repair Tape | 35 mil Total Thickness - EB-RG020-50R - One-Step Durable, Waterproof and Airtight Sealant - Image 1](https://m.media-amazon.com/images/I/813CFvFsU7L.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked Fantastically *by S***K on July 31, 2025* The roof of my enclosed trailer started leaking.
