Older post I know. But figured I would give my .02 . That looks like a SUPER easy buff job and I wouldn't even be worried about it. When the time comes to tackle it this is what I would do. If they are just surface scratches (which they look to be) I would use a 3000 grit trizact 3M pad. Soak it in a bowl of water with a couple drops of rubbing alcohol and a drop or 2 of dish soap for a few minutes. wet the area you want to work on. lightly sand on it with the 3M pad for a few seconds and then squeegee off any excess water. You should be able to get an idea of the uniformity of the surface and know if you need to sand more/ how much effort is required. It is really hard to sand to much with the technique, you would have to be pushing really hard or sanding for 10 minutes straight or grinding on a body line to burn through your clear coat. People just get scared of the idea of doing it themselves and hearing sand/paint in the same sentence will send them for the hills lol.
After that you can move on to buffing...small areas you can get away with by hand but if you get into a big area a variable speed buffer will definitely make the job go faster and easier. If you do by hand use a microfiber towel. If you buff use a light cut foam egg carton pad. Buff at around 2000-2400 rpm's for your initial cut. Then when you see the shine coming on (only takes a couple of pass's when using my trizact method) you can drop the rpm's down to around 1200 and do a few slower lighter passes.
As for rubbing compound I love using the Meguiars products!. I prefer their tan bottled Mirror glaze products. very little goes a very long way!. Once you are done I would follow it up with a rinse and a nice Meguiars paste wax and I guarantee your paint will look better than brand new!.
It might sound like a big chore but I have done TONS of jobs with this exact method have never had 1 complaint. And I must be doing something right since my 72 Plymouth Duster I restored and did this way landed in Mopar Muscle Magazine. With the job your are looking at doing I could typically do all 4 wheel wells from start to finish in about a half hour. So like I said, It sounds like a big job but it really isnt that bad.
Sorry for the long winded response but I figure maybe you would still be interested in some info or maybe someone else that stumbles across this thread.
