Learned that one the hard way on my 02 dodge. Used armor all on the dash and it craked down the middle after two years.Auto Magic Magic Dressing. Put in on with a sponge, wait, wipe off excess with microfiber towel. Shiny is not a good idea up there and will eventually cause the dash to crack. Ask Ram owners, Hummer owners and any classic car dash. Armor all is terrible. Magic Dressing will give it a little luster and make it easy to get the dust off without being greasy!
