Thanks for the comments guys. Actually the paint hadn't been buffed out yet in the third pic. The tin is Humbrol #19. It definitely takes longer to dry than most paints though. I let it sit for a good 4 days, before trying anything. On the next one, I will let it set even longer as even after four days it still felt kind of soft. I decided I would try this buffing technique just to see if it really made any difference, and also to remove a couple minor flaws, ie. dust specs from the hood. It did look ok, but I think if the builder just took his time and had a good paint job to begin with, he/she wouldn't need to buff anything. As I said, earlier, mine was just to see if I could, and to remove a couple of dust specs. As to the carbon fiber decals, Tamiya doesn't provide for that option in the kit. However, I bought two sheets from Scale Motorsports of two differing colors of carbon fiber, and also some seat belts to use on other builds. They are a nice improvement. The sheets should provide one with enough to do a few cars depending on how extensive one got with the application.
The buffing system I used was from Micro Mark. I started with the 3600 grit pad, then 4000, 6000, 8000, and finaly 12000. This was followed with the Novus polishing creme/light scratch remover (#2 bottle) and then the #1 bottle for the protectant and shine. As far as a suggestion on using it, rub the sanding pads in one direction only, ie. front to back. No circles as this makes it hard to remove the scratches, and also creates an uneveness. When you get to the point of using the #2, and #1 bottles though, these are the same as applying regular car waxes, "Wax-on"-"Wax-off", small circles. Also, I suggest trying it out in an out of the way space to see if you are getting the results you want, then proceed to the main areas of the body.
On the next car of the same build, I will use a good amount of the carbon fiber decals, so keep your eye open for it. Thanks again. for kudos, guys. "Q"
