Dual Purpose Does Not Work
Ultimately the dual wash and wax products have the same issue.  It seemed to have some washing properties to remove dirt and grime, but so does water when sprayed from a pressure washer.  The wax portion of the product leaves visible streaks.  The RV that this was used on was a newer RV and after using the product it had to be hand washed and then hand waxed.  It left the RV with a lot of streaks and haziness and overall made the camper appear dirty.  After using a different product to wash and then a separate product to wax the RV came away with a perfect shine.
