OlFart describes the minimal method that is about the best you can do without removing the glass. I know from experience with our previous coach, a 2002 Journey, that if you can see rust when you pull out the rubber molding, there is a lot more behind the glass that you cannot see. However, it may be years before you develop a leak or the glass breaks.
