SOLAS Marine Reflective Tape: We’ve been using 3M’s SOLAS reflective tape for several years. It was designed for the Coast Guard to use on life jackets, so you know it has to be tough and withstand time, bad weather and wet conditions (SOLAS = safety of life at sea). It is a bit expensive, but it is the brightest and most durable stuff I’ve ever found. [Hmmm.]
