Quick answer: Car Builders Seal It is a black, self adhesive butyl sealing material that stays flexible and waterproof. It does not cure, so it forms back into itself like a gum. Use it to refit door card membranes, seal headlights, seal seams and joints and stop panel rattles. It is rated from minus 50°C to 130°C and comes as a 6mm diameter bead, 10m long.
Butyl is a soft, sticky rubber that never fully hardens. Pressed between two surfaces it grips metal, plastic and glass and stays pliable, so it keeps sealing as panels move and temperatures change.
One roll is 10m. Measure the edge of each membrane, light or seam you want to seal and add it up.
Seal It is not tied to any make or model. Car Builders list door card membranes, headlights, seams and joints, and rattling panels.
