My 1997 Trooper shows Silver Metallic for the trim color. I've purchased a touch-up size container at the dealer and it doesn't match. The color from the dealer is much more like aluminum and not the color of my trim. Your best bet is to find a local auto paint supplier, they can look at it and match it plus they can give you helpful advice. I buy a lot of things on the internet but you can do a lot better at your local paint shop than online.
