Sadly, that's ALWAYS when someone hits my car, just after I buy it! Unbelievably, that has happened to me 3 times! So I just started buying USED cars!! Haven't gotten hit since, knock on wood! And yes, you are right, everyone is in a big hurry all the time. Also, you might consider using some kind of push pins, they look like staples from a staple gun but longer. You can get them at wal mart in the fake flower dept., just ask one of the ladies in the fabric dept. where they are if you can't find them. They will probably hold well in that styrofoam stuff. By the way, if they are too long just use some wire cutters and cut them to the length you need.
