What do you use for a detail spray!

I have bought some expensive stuff with big specialty names and was not happy any of them for ease on and off and overall performance. Tried a lot of them but have found the cheap stuff from Walmart to be the best. Been using it on the Barracuda since 2015. Was washing the coach today and even found this takes the black streaks right off with the same easy on and off application. Fairly cheap and works great. The special RV stuff pales in comparison.

The coach is full paint base/clear but the black streaks off the roof still do not wash off easily. This stuff removes them and water spots/streaks.
