Fuck yeah. Im actually overdue for that whole process again. I last clayed late summer 07, the year I got the car. I think. Ive only got 5400ish miles and its garage kept. But, Ive washed a few times since then so its just time to do it. Ive got some water spots from when I had to wash in the sun once to remove a lot of "barnyard spew" that had dried in.
Also, keep in mind, Im the guy who "took the car apart" to clean it when I first got it. Fascias, wheels, rocker trim, rear side markers, bumper supports, inner fender trim, etc.
