there are 2 little incy tiny little mini chips outside the rear passenger door right inbetween the wheel well that has rust they are super super small but i hate to notice them when up close and i know the damage rust can do what should i do ....just sand it down w/fine sandpaper and touch it up or what....also what is that stuff called that you put over touch up paint that is supposed to work good. i cant think right now...again these are super small like 1mm diameter
