Does not work.
Do not use this product. It has left my RV all splotchy. It looks terrible. I am trying to find something that will work. I wish I had never used Poly glow to start with.

This stuff is amazing! Made our camper look brand new with the polish they sell in this brand. Would use nothing else on it.
