Sanding or polishing die-cast metal parts

Posted in Custom Workstation

Hi guys,

I'm trying to smooth out die-cast metal armor parts for a set of figures I bought.
Basically, the surface is a bit rough right now and I want to be able to re-do the gold finish on it and make it a lot more shiny.

What's the best way to go about this?

I do have a rotary tool now, with many types of attachments.

Thanks cowboyink,

I think my kit has a deburring tool as well, I will try that.

A bit of correction on my previous post:

After stripping off the clear yellow coat on the diecast metal piece, I confirmed that the
any surface imperfection WILL show up through the top coat.
So, I DO need to smooth down/polish up the metal after all.
In fact, if the metal itself gets shiny enough, I won't need to bother with Killer Chrome-- just repaint with clear yellow coat, and that's that!

So aside from the deburring tool, are there other attachments for polishing die-cast metal?? Anyone???

I just happened to be on when you posted
okay my dremel kit came with a "soft" de burring tool kinda feels like a dense foam disk. I use it to take paint off of figs I messed up, but I found that if you put a little pressure on it it will take off material in small doses.

I am surprised that you know the title of the anime...
It's unfortunate that the American company that did the dubbing & censoring did a HORRID job
and ruined it for everybody in the States. The series was pretty popular in Europe and some South American countries.

Anyway, the basic concept of these figures is that the armor each character is wearing (called a "Cloth" can be put together into an "object" form that represents a Constellation.
The character here is the famed Saint of Sagittarius, of which the original constellation is a centaur.

Here's the object form of Cloth of Sagittarius:

Anyway, the figure in this pic looks very well detailed, probably for promotional purposes.
I want to get rid of little blemishes and imperfections that came on mine.... hence this post.

Is that figure from the Knights of the Zodiac cartoon? @_@

Wow cowboyink,

Thanks for a lightning-quick reply! (that was, what, 2 minutes after I posted??)

So this is a figure of a character from an 80's Anime...[I know anime-fans are in the minority on this forum, but please bear with me...]
The armor pieces are made of either die-cast metal or plastic.

From this close-up image, you can see the "graininess" of the chest and hip plates, which are made of die-cast metal.

Here are some of the metal pieces from the figure.
Please observe the "pockmarks" on the hip plate (right), and the cast lines running down the middle of the two other pieces to the left.

Basically, I'm trying to get rid of the cast lines and maybe the pockmarks by light sanding with a dremel tool.
My current strategy is to then use Killer Chrome from Alsa Corp, to coat it mirror-finish silver, then put candy yellow clear coat over it to achieve the shiny gold effect.

So, I don't need to "polish" the metal itself to a bright sheen-- I just need it to be smooth enough so the Killer chrome spray can coat the surface evenly.

If what I'm planning to do is not insane, what attachment would you use to smooth down markings/blemishes on the die-cast parts???

can you post a pic? I've had some metal polishing experience as Im sure Kyle has from his time in a body shop. If you post a pic I may be able to point you in the right dir. if not give a little more detail, like is is detail you want gone? what kind of metal is it? is it flash you need gone?
