A roll of plastic trim with shiny silver "chrome" insert to cover the rain gutter. It works best with pre-1979 classic Minis which did not come with a rain gutter trim. Due to European manufacturing restrictions, the finish is best described as shiny silver. Length is long enough for one Saloon (sedan), but not for long-wheelbase models (classic Mini Van, Estate, Pickup).
