I have a RS and I remember reading something about this in the ZL1 manual.

Hood Air Extractor
It is not recommended that the air extractor on the ZL1 be waxed, as it will change the gloss level of the surface. In addition, care must be used when waxing around the extractor. If a small amount of wax is applied to the extractor it can create an irregular appearance in the surface of the panel. If wax, debris, or other materials create stains on the air extractor, see your dealer for the recommended cleaner.
