will moorefield,
You should also get the Z18 claybar, the Z7 carwash and the Z6 Gloss Enhancer. I too have a black on black Bird and the claybar is definately needed for the first application in order to get all the small particles off the paint. The Z6 is needed to get the small amount of residue off after you do the Z5/Z2, it really makes the car shine.
When I did the car the first time I clayed, 2 coats of Z5, using Z6 between both and then 2 coats of Z2 with Z6 in between, finishing with Z6. This is a two day process. They say not to do more than 3 coats in one day. Also use the accelerator supplied, it greatly speeds the curing time.
BTW, I don't have you listed in the database, please see my thread "Database Info for the New Birds - post here Update 1", thanks.
