Well I bought the Meguiar's and it is much better than the Armour All products I've used in the past. With both the regular Armour All and their tire dressing, as soon as I drive away the damn stuff comes out of every nook and cranny and spots up the side of the truck. Since its black, it shows every spot like a neon light! The Meguiar's didn't come off like that and I am quite happy about that. A little did spray up on the sides of the truck this morning because of dew developing on the tires overnight. But the spotting was minimal and the tires still look good.
