I see you have something figured out, but for anyone else reading, I'd have to say, if you've never buffed a car, DO NOT EXPERIMENT ON YOUR CAR!!!!! You will regret it. And if your gonna buy a buffer, don't go cheap. Get a variable speed, def. keep it below 2000rpm until you learn the ropes, and IMO don't use a wool pad unless you have to (wet sand scratches). I've wetsanded and buffed cars for almost 10 yrs and have always used a Dewalt w/ no complaints. Decent price too.
And also, to quote an earlier post...buffing a car should not be an all day job. Sure its good to take your time, but there is no reason it should take more than 3 hrs, even for a novice. I was 15 when I started and if it took me all day for one car, I'd be out a job. I was basically alotted 5 hrs to wetsand, to cut w/ a wool pad, and foam pad w/ a swirl eliminator. Its def. not hard to learn, just need to know what your doing and learn the basics from someone who knows
