![]() A hard reflector, like a raised pavement marker, would be best, in that it will last a long time, and reflects in colors. Reflective paint will also stick, but will only be white, so if that is ok, it is a solution. Also, since the rock has a rough, porous surface, a reflective coating will stick very well to it and last indefinitely. The downside to retro reflective paint would be that it only reflects a white color, whereas reflectors and tape will reflect other colors.įor a road surface, reflective tape may stick, but would not last very long. If a grey paint was used, the rock would be very bright at night, but would look very much like just a rock in the daytime. ![]() Reflective paint could be used to coat the entire surface of the rock, top, bottom, back, and sides. The surface is not compatible with an adhesive product like tape. If enough pieces were used, it may outline the rock, however, it would look strange, like a bunch of reflective band aids. So several smaller pieces would be needed. Reflective tape could be adhered to the rock, but the issue would be how to get a sheet of reflective tape to conform and stick to a rock, given the uneven and rough surface. Reflective Paint – Silver Metalized Beads This may or may not divert them away from the rock. The reflector would show that something was there, however, it would not outline the object and show what it was. Or the rock could be coated with reflective paint.Ī solid plastic reflector would mark the rock, but would have to be glued on so that the reflectors face the oncoming car. Pieces of reflective tape could be applied. A solid reflector could be glued to the surface. A reflective application of some type would solve this problem. It would make sense that a rock or series of rocks that run along a road would need to be visible to approaching cars for both safety and liability reasons. One simple example is the idea of making a rock in your front yard reflective to approaching traffic at night. But a closer look at the products reveals distinct differences that separate uses and applications. All end up on the surface of an object, create retro reflectivity, and make it more visible at night. On the surface, the difference between a paint, an adhesive film, or a hard reflector may seem obvious. More specifically, the object returns much more light than what surrounds it, creating what we know as contrast, and contrast is the reason we see individual objects. ![]() This simply means that when made retro reflective, the object collects light from a source, and returns it back to that source more than it returns it anywhere else. Retro reflectivity is often used to make an object more visible at night.
