I want to polish and seal my golf (black metallic) next month.my conditioner would take the nano-sealing of cook chemistry. he meant if the car is freshly polished and the nano-sealing on it is then the paint would be really nice deep shiny. therefore my question..has someone put the cook chemistry nano-sealing on it? stop her also what she promises? deep gloss etc. does the water really run off from the paint?
