OK, I have a dremel, and I tried to polish between letters, but ended up with a blacker mess than I started with. Is there some attachment (wheel) etc. and polish combo that works best?

polishing takes lots of time, just be patient and use the crap out of that dremel

a VERY long time.....

Lots of patience. Way more than I posess.

ok i know some pepole dont like my ansers,but i do alot of polshing. the dremel is the best way to do this project.you need to get a few polishing bonets for your dremel and most tool shops will have and some walmarts.
1:4 small cone polishing bonets
2:4 small dome polishing bonets
3:4 small flat polishing bonets
4: white and red bricks of julers ruge( julers ruge is a polishing compound that is used on gold and silver when they come out of the castings to level them out and make them bling bling.)you use the red brik first then the white.
these tools will make it go faster for you.
when i did one for a friend of mine the hole cover only took me one day(9 1/2 hours) so you just got to keep polishing and wiping it off and reepet over and over.

hey buddha, do you have any pics of that valve cover you polished? I'm thinking of doing this myself but i want to make sure it looks nice- otherwise i'll get it chromed.
