Used my DA polisher to compound, polish, and wax with Meguiar's products on 7/4/19. For a couple weeks I used some waterless car wash from Amazon then since then its occasional touchless car washes. No thorough touch washes at all, it's usually pretty dirty. Garaged 3 days a week, the rest in our brutal heat. I have to say, I'm impressed.
First pic is what I took after the rain today at the grocery store. The other 2 pics are after I waxed it last summer.
