Well I am gonna take the aux. fuel tank, fifth wheel hitch and all off the deck of the bed on my Little Red truck.
Then sand blast and spray a good coat bedliner on it.
While I have the fuel tank/toolbox out (smooth aluminum) I am PLANNING to polish it.
Over the years a lot of the paint has been knocked off by various things I hauled or put on it. Those areas are starting to rust, I figured I had better do something to stop the rust and make it last a loooooooooooong time. (Besides, it will look better

)
