Scothbite is a very irregular grit - bad juju!. 600 grit wet/dry sand paper is the way to go.
Why does your cleear coat have to be matte, aesthetics?
The thing is, if you have rust in the pitted paint, just painting over it will not stop the rust growth.
Watch out that the solvents in the clear coat (paint) do not soften the decals and cause them to lift.
