Yep. Jet Black is a PITA. Everything on black shows. The last 4 posts sum it up. I can remember the first time I washed, claybar'd, washed, waxed....I noticed a bunch of swirls and thought I marred the heck out of the car. The color is tempermental and difficult to keep swirl free. This is the reason some stay away from black. It will require twice as much TLC, then some, compared to all other colors. Good luck!
