When I bought my 3, the body shop department installed my side skirts. What I want to know is whether or not I will experience future rust out problems as they had to drill holes on each side to install these. I did ask them to apply paint on each drill hole but there is no way of telling. I can only see one drill hole (the very first one closest to the front wheel as I open the door and there doesn't appear to be any paint on the hole). If these holes start to rust I am afraid the clips will stop holding the skirts and they will start popping out. How long do I have before that starts happening and is there anything I can do to prevent that from happening? Thanks for all the input.
