In the "Guide to Detailing" handbook from Autopia on their section of waxing/sealants they comment regarding dark colors - " Black cars can look a little sterile or silvery in the direct sunlight. And, the mirror-like polymers can collect minor swirls and actually highlight paint flaws." With Black Saphire do you think it's a good idea to go with Zaino or would you recommend standard polish/wax (+/- via Orbital polisher) due to the above concerns with sealant. Which would yield better results?
