When I polished my cbr covers, I put buffing wheels on my bench grinder and used emory, tripoly, rouge, and jewlers rouge to pollish (there might be others, its been a while since I did it). You can get the buffing wheels and compounds at any home depot in their tool corral. they come as round sticks. the buffing wheels are great for polishing contours and lettering. just be careful not to burn the finish and use only 1 compound per each buffing wheel otherwise its not going to work well. it pollishes fast, hope this helps. :beer:
