Just picked up yesterday a sheepskin wash mit, BMW wheel cleaner brush, and BMW car shampoo.
I looked for the P21S shampoo, but the dealer said you could not buy the shampoo separate from the P21S kit which includes wheel cleaner and wax.
Is there anyway I can get just the shampoo from another retailer in Philadelphia? I just want to try it and see the results. BMW brand on my car and the P21S on the Z3.
