I found and use a product; Blackout Tape, a TrimBrite product a division of Spartan at Advance Auto. It is a pretty easy, very low cost way to improve the trim. I carefully cut it to width, in 3-4 foot lenghts, get another set of hands to help lay it right over the old trim. Yes, the old rips will be visible upon close inspection, but a very big improvement. Be careful not to re-pull the tape up, it will rip the old trim worse! The tape has held for 6 months, the car is basically garage kept. Worst case, try a small section to see if you like it.
