I've got a mazda3, it's pearl grey. I would like to black out my taillights. However, I've got a preferred method I would like to use. I would like to use the snap on covers that I've seen other cars use. I just don't know where to find these. So, since I can't find those I am turning to the mazda247. Community to direct me with some info. Before I go searchi g through the depths. Of hell. For those plastic covers, should I just do spray or vynl? Which would you do?
