Too much concentration will strip any wax you have on the paint. The wax that is included in the ';Wash and Wax'; isn't worth much for protection so yes, it is harmful. Remember, it isn't really benefiting you much to use higher concentration levels. One mostly unknown tip is that the actual water in the wash does 90% of the cleaning. The soap is mostly for surface lubrication to prevent scratches and swirls.
Since you have to rinse it off when you are done, it won't hurt. You are just wasting the stuff by pouring way more than needed into the mix.
