I do give the nod to 1000P for appearance , but the 845 with its ease of use , durability and looks that are softer than 1000P , but really just a different appearance , and it does not stain my grained trim . I brought the shimmer back up with using some AW or a qd , but it still looked great even without the fresh waxed look. Sheds water and dirt very. I also have a coat ( just one ) on my silver Rav4 and that was a few months ago and the wife has ran it through many carwashes and it shines beautifully . She maintains wipedowns with 425.
