Endurance is wonderful for tires, but far too shiny for normal BMW trim that is supposed to be a matte black. I did use the stuff on window seals and it worked well, but it was very shiny. Black Again is what I prefer for most trim. Back to Black is good when the trim is badly faded. Sonax cockpit spray is great for interior plastics. It is anti-dust and doesn't leave a gooey film.
