The exterior design of the Volt seems to consist of many flat sheets attached to the body in such a way that leaves many channels about 1/4 inch wide. This can especially be seen around the rear tail lights. When we first got the Volt we saw there was what looked like white powder (wax?) down inside the channel making all the edge pieces around the light look the edges were crazed. We chalked it up to a sloppy detailing job where excess wax was left over. The problem is I have no idea how to get inside there to clean it. (I really don't want to take a tooth brush to it on a daily basis.) Now that we've had the car for a couple of weeks I see that road dirt tends to accumulate here as well.
Will I have problems in the Winter when water gets into these channels, freezes, expands and breaks something?
