The bottle also states its a CLEANER. Not a dresser. It will clean the surface and bring out the original appearance. The protection is NOT a priority with this. For that, u need a a dedicated dresser
Here's another example. A wax/sealant will protect the paint better, longer and look better while a quick detail spray will work on the same basis only for a shorter time and may not give the same appearance since its a detail spray and not a wax/sealant. you can help remove light layers of dust from your car using a QD but you can clean your car with a wax/sealant. See the difference?
If you still dont understand, too bad. Look into Megs interior dressings. then find out what their purpose is.
