An interesting read on the “topical application of retro reflective microspheres (glass beads). The concept is that you are essentially making your chosen item reflective via the same manner that your local Transportation Department makes painted stripes on the roadway reflective.” Photos and instructions and links to other high-visibility reflective materials/tips included.
