Sure, it's easy.
Depending on the depth of the scratch is where you may or may not need sandpaper. Sand with the grain, usually in the length of the pipe.
If so, use some 250 grit, followed by 400, 500, 800 and maybe 1,000. You can really judge by looking at your work and what scratches are left and how high of a polish you want. You'll need to blend the shine with the rest of the pipe.
For polishing- put one of the bobs in your drill. Hold the corser polishing compound (usually the brown but, see what the instructions are) in one hand and the drill in the other. Rub the bob fairly fast so the compound actually gets warm enough to slightly melt it into the bob. Stainless takes a little more heat to polish than mild steel or aluminum.
After this compound buffing, place it in a baggie and mark it "BROWN", and only use it for that purpose. Wipe the pipe clean. Do the same process with the other compounds until you achieve the shine you like. The white is for the final buffing. For the end result, use something like Mothers Billet or the Mag wheel product. Wipe all the compound off the pipes with a soft cloth and water. And your done !
Keep the compounds and the bobs separated, so you don't contaminate them with each other. Then place all of them in a tightly tied baggie for storage and mark the bag for each color/grit compound.
It is quite easy. And let me know how the process is going.
