If the scratches are down to base coat, you wont be able to remove them. Filling them and then sanding them smooth may work, depending on the base coat, a metallic base will show flaws more than a solid base. Wet sanding inst that hard to do, the idea is to smooth out the blemishes and give the surface multiple directions for the light to hit it so when you polish it, you are less likely to see any scratches. If you want to practice, start up on the roof at the back of the cab to get the technique down, that way if you mess it up, no one will see it. Just remember to use light pressure and only go so far as to smooth out the surface, and never let it get dry on you, always work it wet, Its OK if the residue dries when you are finished with an area, it will wash right off. You can polish it by hand if the buffer scares you, and you probably wont need to do the entire truck to make it look good. If its really bad where polishing wont help, then a good scuffing with 3m pads and wax/grease remover will prep the surface for a recoat of clear. As long as the base coat isn't scratched, then a fresh coat of clear can go a long way and is not that expensive as long as the prep work is good. Prep is the most expensive part.
