I was able to remove my antenna and the big, black base. However, there is still a small hole that's a little more than a centimeter long. Looking through the garage for cars that are the exact model as mine ('09 LT Sedan) a found a few that didn't have an antenna or base.

This one didn't seem to have any sort of hole at all. So my question is, how should I cover up this hole? It seems like others have done it so it should be possible; I'm just not sure how exactly to do it. Any ideas?
