So that it doesn't leave scratches on the metal?

What grit should I begin with and end with? And in what order?

Do I go from highest grit to lowest or visa versa?

My truck has both surface rust and deeper rust on the body.

Sandpaper will not be the most effective means of removing rust, even surface rust. 3M makes a good wheel that is like a stiff Scotchbrite pad that is excellent at cleaning surface rust or a little worse. Deeper rust requires either neutralization, media blasting, or cutting out and replacing.

As for grits, generally you start with 80 grit on bodywork and end with 180 or 220 when using a good filler primer. If you use a lacquer primer, I would finish with 320 or better since it doesn't have good filling properties.
