I strongly reccomend that proper care is used when "detailing" a car. Due to lack of knowledge and plain old common sense, many service stations and Car Detailing employees end up causing damage to the finish. Remember that any surface, particularly a painted surface is extremely vulnerable to damage.
Things that seem as harmless as washing and waxing can cause damage. A simple act of drying out a car can cause damage if the surface of the car is not 100% free of dust, girt and grime.
I suggest that youyou clean ur beloved car yourself to maintain its good looks or get it done in your supervision.
We all have seen brand new cars ( less than 3 yrs old but do not have shine in them. Why?? The reason is improper washing, waxing that eventually dulls the surface and causes visible and not so visible scratches, eventually making the car look old
