## Description

Review: Good quality, sticky and flexible - The 1/4 inch butyl cord I received was good quality and appeared fresh. It was a round cross-section "cord", and not a flat tape. The butyl cord was very flexible and sticky, but not so sticky that it would not let go of your fingers. I applied it at about 70F degrees and kept it out of direct sun so it would not get too soft. I used the cord to seal around the base of some outdoor wall lights that did not fit snuggly to the wall. It worked great. I could push and pull the butyl cord into shape to fit the crack between the light base and the wall. Should provide a good seal from weather.
Review: Works like a charm - Works really well. Glad I got it. Helps keep water out in my truck bed with Tonneau cover in
