Eternabond's microsealant technology creates permanent, waterproof bonds for RV roof repairs, seam sealing, and leak prevention. Unlike traditional caulks that dry out and crack, Eternabond tape products form a molecular bond with roofing materials that actually strengthens over time. These tapes work on rubber (EPDM), TPO, fiberglass, metal, and virtually any other RV roofing material for repairs that outlast the roof itself.

What to Know Before You Buy

• Surface preparation is critical—Eternabond sticks best to clean, dry surfaces, and their prep products ensure maximum adhesion.
• Different tape widths suit different applications: 2-inch for small repairs, 4-inch for seams, wider tapes for large areas.
• RoofSeal (white) is most common for RVs; DoubleSeal provides gray color for metal roofs or less visible repairs.
• The bond is permanent—applying carefully the first time matters because repositioning isn't possible once it's down.
