## Description

desertcart.com: Better Boat Butyl Tape for RV Roof and Boat, 36 Feet Black Putty Window Sealant Tape, Waterproof Weather Resistant, 3/4 Inch Wide x 1/8 Inch Thick : Industrial & Scientific

Review: It is sticky - Works great enough to do five small windows
Review: Outstanding sealant! - This stuff is amazing! It creates a great seal. It’s very sticky and stays in place while assembly is being performed. Better than the gray butyl tape from big box stores.

## Features

- 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.
- PEEL THE LINER AND PRESS TO SEAL, NO GUN NEEDED: Remove the PE liner, press the putty compound firmly into the gap, and smooth it flush. No mixing, no caulking gun, no cure time. Bonds to fiberglass, metal, rubber, vinyl, and wood on contact.
- 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.
- WARM THE PUTTY BEFORE APPLYING IN COLD WEATHER: Below 60 degrees, knead the tape in your hands for 30 seconds. Cold butyl stiffens and conforms less evenly. Better Boat is a family owned American company based in Miami Beach, Florida.
