This Instructable will cover the topical application of retro reflective microspheres (here on out known as 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.
I chose an easy part of my bike to "reflectablize" as one of my friends would say. A detachable fender that I mostly never detach.
Before we begin, I must state that I tried the two main manufacturers of "reflective spraypaint" on the market. Those being Rustoleum and Krylon. The amount of reflective material in the spraypaint was almost non existent. I found that I had to do way too many coats to even get noticeable reflectivity. I ended up seeking a refund from each company. Therefore, I strongly advise you NOT to waste your money. You could always go the reflective tape route but I found it to be expensive as well and just didn't seem as cool as what I am about to instructablize you on.
Step 1: Materials list
1) The part that you want to reflectabilize
2) Krylon Clear Acrylic Coating (or similar clearcoat paint)
3) Masking tape (if you need to mask anything)
4) Paint tray or suitably sized object to catch glass beads
5) Empty spice shaker
6) Any necessary tools for disassembly of bike part
7) Retro reflective Microspheres (glass beads)
