I have seen the product bundle previously used about 5x to my vehicle after rainfall to clean fast times. The handling is very easy, the luster extraordinarily and sealing for the next rainfall also top. The dry cleaning process takes (in an SUV) about 20 minutes and makes the car seem as freshly washed. Since I use the bundle, I avoid the wash, since the cleaning is gentler and a monthly hand wash in the washing box since sufficient.
