Butyl Tape, RV and Marine Window Seal Kit, Gray Double-Sided Putty Tape, 1/8" x 3/4" x 36 Ft, Waterproof Rubber Caulking for Boat, RV Windows, and Outdoor Sealing

STOPS WATER BEFORE THE DAMAGE SHOWS INSIDE: By the time moisture stains a ceiling or warps a wall panel, it has been moving through the framing for months. Seal every roof seam, window frame, and hatch edge before the first rain of the season.

EXTRA STRONG WATER RESISTANCE: The 1/8" thick by 3/4" wide sticky putty butyl tape will seal irregular gaps and cracks to create a vapor barrier and keep unwanted water in or out as a strong thick putty sealer. Can withstand up to 290°F for years.

36 FEET PER ROLL COVERS A FULL JOB IN ONE PASS: Most butyl tape is sold in 10 to 20 foot rolls, which forces splicing partway through the job. Every splice is a potential leak point. At 36 feet, most window reseals and roof jobs run end to end.

STAYS PLIABLE LONG AFTER SILICONE AND CAULK CRACK: Silicone and acrylic caulk harden and crack when surfaces flex or temperatures shift. Butyl putty compound stays permanently flexible, conforming to gaps as the vehicle moves and seasons change.

CHOOSE YOUR COLOR TO MATCH THE SURFACE: Available in White for bright window frames and light trim, Black for dark rubber seals and tinted frames, and Gray for aluminum trim and factory gray finishes. Select your color above before adding to cart.
