The pits/scratches are even more noticeble, they are filled with black residu. I also tried sanding with 120 grit paper but they are still there. I heard that greasseles is like sanding exept it is much faster and effective. If GREASELESS can do the job of sanding them down to a smooth even surface ready for power buffing please outline the steps i should take

You could experiment with a setup wheel(s), which is a cotton wheel impregnated with glue and abrasive. Caswell sells the makings. If you use a thin coat it will be a bit flexible and not gouge. Use it on a 4" spiral wheel with your drill (a cheap drill will burn up quickly, however). It will take some practice to avoid gouging, but what have you to lose?
Start with 120. After that, you'll have to go by hand with 220 and 320, maybe 400 or 500, or else use greaseless up to 320. Once the surface is smooth, the greaseless will work much better and last longer. Use a little white rouge on the greasless wheel after it sets up - that will prevent an orangepeel surface. Work in different directions as much as possible to reveal the scratches.
Good luck. A lot of work but cheaper than new wheels.
