I won't lie; not every job is a night and day difference and not every job is hard. That doesn't mean there isn't a job that isn't important. This brings me to a very new, low mileage, 330i. This car is not daily driven but the owner wanted to make sure that when he does take it out, that he won't have to worry about UV or chemical damage and of course, wanted extreme gloss. That is why he went with Opti-Coat Pro, a lifetime coating with a 5 year warranty!
