Zaino for wheels is a painfull option and this is why:
-it has no cleaning properties
-you need at least 2 products, Z1 and Z2 or ZFX and Z2 to ensure it bonds to paint
-on wheels it lasts no longer than any other polymer product
AIO works well on wheels but if you don't want to order online and wanna save some money try NuFinish, ~$5 anywhere. It does better job cleaning brake dust and tar from the wheels than AIO and lasts a long time. It has very harsh chemicals, lots of solvents and that's why it does so well on tar but for this very reason I wouldn't use it on my car's paintwork.
