2) Help a guy who's not too tool savvy. Which dremel, which head, and which polishing compound?
Thx
I use 3 compounds (I have a 4th for a ultra high mirror polish, but don't need it with the results I'm getting).
The colors (in order of use) are green, blue and pink. They have different levels of "cutting/polishing". I also use a seperate wheel for each compound, and all 3 wheels are different. The wheel for the green compound is the hardest of the 3, and the wheel for the pink compound is very soft, used for finishing.
You can use any rotary tool which has at least 5000 rpm. Perhaps slighly lower would work, mine has a control for varying the speed which is even better. It didn't cost much, about £15 if I remember correctly. You only need to use a little compound at a time, if you use too much it wont polish properly. The idea is to use a little (touch the compound with the spinning wheel for 1 second) and then polish, and then re-apply the compound freequently.
It takes a bit of practice but you will get the hang of it, your polishing technique will also improve over time, resulting in a pure mirror finish with little or no swirls/marks.
Good luck
