The idea of a set package for Opti Coat is absurd. Applying OC over any kind of marring is a waste of time, imo. Even new cars run the gamut from "mostly ok" paint condition to "stupid terrible". Unless it's a previous client I always ask to see the car before OC or leave the quote open ended until I see the car.
Check out this new cars... imagine alcohol wash (whatever that is) then opti coating them....hah.
