Get a box of 220 and a box of 500. That's the grit count (grains of sand per square inch I think).
If you have a garden hose that helps but a bucket of soapy water works too.
Using one of these is suggested, but depends on the contour of the piece you are working.

Take all of these things, and start with the block and some 220. Dip the 220 in soapy water (or run the garden hose over the piece you are working). Work the sandpaper with the water running (the water flushes the paint so it doesn't clog the sandpaper).
Work the 220 until most of the big scratches and the clear is mostly gone. Don't work all the way to seems in the parts. Another words don't go to the edges where the doors are and where the trunks seal etc.
NOW give your car a good rinsing with clean water. Start with the 500. Do the same with the 500 grit paper as you did with the 220. Try to cross hatch it (do strokes perpendicular to each other). This step should take out most of the clear.
One thing you should NOT have when finished are areas that have flakes. If you have a flake under the base coat your base coat is probably gonna pull up. If you encounter stubborn areas you can sand in one direction away from the higher build area.
^^^^ BUT take all this as a grain of salt i'm only a hobbyist not a professional. Regardless this is what I'd do if I had about $1000 to spend on a paint job.
