Ron,
If you buy your buffing compound from anyone other than a company that specializes in buffing compounds you are not going to get what you need. You will get an “all purpose one size fits none” product that the salesman will tell you will work fine (remember, never believe anyone that is trying to sell you something). You really need several compounds designed for stainless steel and each one designed to buff out the lines left by the previous compound. You will also need different wheels as you change compounds. Buffing compound companies advertise in magazines (check Hemming’s). Frequently people show up at large swap meets selling buffing compounds (are you going to the LA Roadster show?). There is an excellent article on buffing in one or the “How To” books that reprint articles from the restorer. One final thought, as others have warned, be careful.
