Weatherstrips and rubberised linings etc would deteriorate over time as the coating hardens and this would leave the surface psckmarked in time even if you don't go to a car wash as stains would collect whenever it rains and dirt accumulates.
There are restorers available for such components and would leave a coating on to keep dirt and grime away at the same time keeping a new look. Look for tires and lining restorers.
