Reflective paint is easy to apply and is relatively bright. My issue with it is that it looks like I painted my bike with a fine sand. I like using a flexible or stretchable reflective tape. Tapes are brighter and can be removed. Flexible ones will not lift at the edges like the stiffer tape such as 3m diamond grade. I have tried two types of stretchable reflective tape, high intensity and engineer grade. Engineer grade flexible comes in many colors and is brighter than reflective paint. The white is rated at about 75 candelas. High intensity flexible only comes in 3 colors. White, orange and yellow. However, it is 3 times brighter than engineer so you can be seen much further away. I bought mine at a site called tapedealer. I believe identi tape also carries it.
