The 30 year old Truck in Flux has a nice patina of worn paint, sort of an ab-ex painting emerging from many paint jobs over the years.  I keep that intact with coatings of UV clear coat and casting resin, but wanted to add something reflective.  Each side got a nice piece of 1950s Chevy trim, and on one side I added exhaust pipes from a Suzuki motorcycle.  Vroom!
