Just reading about what I could apply to my black car after washing as opposed to wax for that extra shine. I am now looking more at sealants/glaze such as Zaino Z2-Pro which seems to last a very long time for ppl, say it lasts a few months would this replace regular waxing? BTW I would prefer just to apply one product to give it shine as a regular thing so if Z2 pro does this it would be great......
