i use a product called "speed shine" from Griots Garage and so far it looks new. Its more like a cleaner/wax type of product, oops, a detailing spray, sorry. Armour all would run down the sides of the truck when it gets wet.
Todd recomendation also caused me to use the Meguier's Gold Class leather cleaner/conditioner. It works and looks great on the tonneau, black cladding and the step bars. Easy to apply with the wipes. You do have to be careful with your step bars...they look nice but are real slippery! Thanks for the tip Todd.
