BLACK STRIP CAULK DUM DUM

3M Strip-Calk never hardens or becomes brittle. Seams stay smooth and gaps stay filled. It is also self-adhesive and non-shrinking, which makes it excellent as a sealer for plugging holes and preventing noise and moisture penetration. It thumbs in quickly and smooths with a fingertip.
