dude those wheels are a pain in the a$$ to clean. I am detailing my pop's navigator(never detailed and is 3 yrs old) and it has the same type. I am using the most aggressive clay bar too! Happy Fathers day present though.
Anyways back to topic. Were there any tough brake dust parts to remove off the wheels?
And good job on paint correction and especially taking on a Jet black 7 series... It usually takes me two days to do a car that huge! And you must be loving the CR spotless? because i am def. enjoying mine haha.
