We have used nothing else on our 2012 Drv Mobile Suite since we purchased it in November 2011. It has never had a water/soap bath, except for rain and when it sat for 2 months on the lot before we adopted it. Yes, you do NOT need any kind of wax product. It apparently has UV protectant because we have no oxidation, it looks like new. When it rains it beads up like wax. When we travel and the front cap is covered with bugs I spray a more diluted mix on it or just plain water (oops, I do use some water) let it sit awhile, then use the microfiber pad to wipe the bugs off. Will never use anything else. The initial kit is pricey, about $250, but well worth it. You get all you need to take good care of your rv. I just reorder the wash wax all concentrate and the black streak remover. Great product.
