I'd vote for that the claybar gets it.
Isnt it funny how we notice things on our cars no one else does.
I was out washing the cars, and my neighbors always tease me. One person said, they look nice, and I said I hadn't washed the 2nd one yet and she said "But it looks clean" and I was like no way it's wicked dirty LOL
I point out minor things to people on their cars, one lady in my complex had a dent on her car for a couple of days. I noticed it at dusk and I pointed to it and it took her a min to notice.
