I've actually gotten it to look nice without people giving me any directions
read all instructions & you need a couple of hours for this:
you need either to disassemble it (an insanely difficult job due to the fact its almost impossible to separate the glass from the metal).
OR
mask off areas you do not wish to polish with masking tape (including, the keyboard half of the phone, under the screen, the screen itself!)
the next steps will take around 1/2 an hour to an hour each.
the paint will come off with sanding (180 grit silicon carbide sandpaper). try to sand in one direction as its easier as you go on. Wet sanding may help speed the process, it might be messy but it helps. be aware you are actually removing material from your phone as you do this, so understand that if you sand too hard on the edges, corners and rim of the metal you won't get a straight effect.
the purpose of starting at 180-200 grit is to remove scratches from your finish so it won't show up on your desired result.
move to 400 grit, then 800 grit, then 1200 grit, then etc etc
the point of this is to remove the previous finish, whether it be paint, or a existing finish. so, as you progress into the next grit, sand to remove the previous grit's scratches. (800 grit's finish should "cover" 400's).
eventually if you do wish to polish it you should sand up to around 1500 or so grit. you will have a matte like shiny surface. the next step is to use "mother's aluminum polish". apply a thin amount and rub. use a cloth. you will have to wipe it clean after it changes color or something (i dont remember this part as I kept my droid in a brushed finish, but it says on the label of the can). your droid will change from a matte-like surface to black, and when you wipe it clean, you will have a shiny, polished droid.
