Whereas Quartz Easy emphasizes hydrophobic's and durability (a stronger version of Moonlight), Quartz Guard favors slickness (slickness helps with coating 'self-cleaning'), as well as comes in a large 200ml bottle (will do at least 10~15 mid-sized vehicles), making a great choice for pro detailers for their customers looking for a 1~2 year coating (depending on layers).

Has a tinting effect making dark-colored paint deeper and white's more reflective.
