allright, im real glad i stumbled across this message board.

i am trying to learn how to polish car parts. so today i went to the pick and pull and got an intake manifold off of a bmw 6 series with the I-6 engine.

i stopped at my local auto parts store and picked up a few things.

gunk engine degreaser
mothers mag and aluminum polish
white cotton terry cloths
variety pack of sand paper which has 320, 400, 600, and 800 grit sandpaper. i had 60 and 100 grit at home.
polishing attachment for my dremel tool

so i set to work on a flat part of the intake. i used the de-greaser and than hit it with a wire wheel in my drill. after that i used the sandpaper on it from lowest to highest grit. i then used the aluminum and mag polish with the dremel tool and polishing attachment to try and give it a final shine. its not what i had hoped. i am looking for a high shine. at first, the surface is very rough due to the casting process. i can get it smooth and get an ok brushed luster look but thats it. there are also a lot of crevices in this manifold and a lot of letters and numbers to polishinside and around.


what should i buy to make this go faster? what will get rid of all the fine scratches and pits from casting and give it an awesome polished finish?

one reason i am doing this is that a friend of mine wants to open up a performance shop, and needs someone to do metal polishing. i need the best results possible so i can help him out.


edit: at this point i only have a drill and a dremel and i dont have any money to invest in a bench grinder.
