I recently (earlier today) read an article on AOL about LifePaint, an clear spray-on reflective paint being marketed in the UK by the automaker Volvo. It is apparently a rebranded version of a product by Albedo100. It is intended to be used on fabric, and has some trouble sticking to plastics, The adhesive that bonds it to fabric washes out with laundry detergent, so it has to be re-applied frequently. It is water-proof. Albedo100 also has a version that is permanent on metal. It can be applied to a bike, and does not change the appearance except when a bright light is shone on it. It reflects light back towards the light source, so it is visible at night to an approaching vehicle with headlights. Any experience with this product? http://www.wired.com/2015/03/lifepaint-reflective-paint/is an article about it.
