Polishing BBS RS....HELP

[44stella]

okay, heres the deal,

i just acquired a set of BBS RS, all the lips have some imperfections, just dirt from what i see, i have sanded using a sanding block by hand, with about 200 grit or so, then i did 400,600,800, 1000, and finally 1500.

after all that there is still some grit or something, but its just not coming out, i thought about a dremel, but i cant muster up the balls to do it, and possibly screw up the grain of the metal, and end up screwing up a part.

basically im asking,
should i use a bit on a drill? if so what?
should i try sanding with a different grit?
after sanding i polished it and they are nice, but not quite mirror, how can i get that finish.

please help

Keep going - use 2000 and finish with 3000. You are wet sanding, correct?

Then you'll want to use an aluminum polish to restore the shine. But more importantly, why are you sanding to remove dirt?

i cant find 2000, let alone 3000, and yes i am wetsanding using wd40 as the lubricant,

i tried the nevr dull but it didnt work as well as mothers polish with a power-cone adapter to drill.

I've never used WD40 as a lubricant for wetsanding - I've always used soap water.

Any automotive paint store will have 2000 and 3000 grit. They'll save you lots of polishing time over trying to remove the sanding marks of 1500.

Let's assume I find 3000 grit. And have it all sanded.

Do I just polish. Or is there another step. Should I buff or anything?

You should be able to find 3000, even if you have to find it on the internet. That is the key to getting the mirror finish. An auto body paint store should have it.

Buffing is polishing. Yes, after you hit it with 3000, you need to polish it out.

Use soap/water as a lube for sanding.
