Kiffsta asked me to give some info on the methods I use to polish bits of my bikes, so this is how I do it (there may be other ways but this is mine). There are probably thousands of u tubes on polishing so have a browse and decide what suits you best. Safety musts are; close fitting clothing that will not get caught in the buffing wheel, eye protection as the soap and bit of pad go every where, old clothes as they get really dirty and greasy, solidly mounted wheel/stand so it doesn't move while buffing. I use three different types of wheel depending on the job. A Sisal wheel for badly pitted surfaces or after bead blasting. A stitched cotton wheel for most surfaces, and a soft cotton (not stitched) for soft metal (eg carbys) and plastics. Sisal wheel. My main wheel mounted on bench grinder. Soft cotton wheel.
