The band has rubber-like consistency, expands well, smells slightly of bitumen, is also reminiscent of this material. Adhesion to metal and plastic surfaces is mediocre Adhesion to itself (when wrapping the repair area) is very safe, especially when the tape spans and easily expands it. The layers seem to merge. Water-repellent qualities are very good, the repair is inherently tightly enclosed, so that no leaks are possible Tearing off by hand does not work, for separating additional tools is necessary. You can pull the band in the length so that it tears, it deforms and thereby becomes unusable. In the opened package dries the band and seems over time to lose its qualities
