we have diamond shield (pretty sure that's the name) on the front of the coach. I clean it after every day's travel, then treat it with the recommended Plexus. After treatment the plastic is pretty slick, but the bugs are still difficult to get off at the end of the day. In addition, Plexus is very expensive.
I was wondering if anybody has done any experimenting and found a good coat of wax last longer, or maybe using 303 protector, or maybe ?????
