What I observed after the first wash today. First off the paint really self cleaned this week. This was after some heavy rains. Water beading was very intense. Even on the vertical panels. Flood rinse sheeted the water right off ready for drying. Megs hyperwash wash used. No drying agent this time as I was trying to get done and working around the sun. After drying paint looked pristine. I did not even have to touch the tires as #253 held up to several rains and todays wash. So in conclusion I really like the 10 min. paint sealant. And #253 is the holy grail of tire dressings.
