Now that my steel wheels are on the way, I had an idea to powder coat them in two colors...centers black and lips argent silver. Question is: Can you do two colors of powdercoat on the same piece of metal? I know there is an electric charge involved in the powdercoating process, and you can't easily separate the centers from the rims, so...can it be done?

For sure, No, but I have seen it done on a test piece. Not a rim.

easy answer is YES, I just did it 10 min ago make sure the wheels are ultra clean and when you recoat, sand the part a little with some 180grit.

The key is clean, clean, clean

Yes you sure can, just have to make sure the area that you don't want the powder on gets masked off good. You can use tin foil for masking off areas you don't want the to be powdercoated. I powdercoated an air box for an EFI two tone powder colors, black and orange. Check my blog, link is on the bottom of page, pictures of the air box are in there.

Mask off the outer section, powerdercoat the inside section.

then...

Mask off the inner section, powerdercoat the outside section.

no problem.

OK. I understand now. I didn't realize powdercoat was similar to spray paint. I assumed that since there was an electrical charge involved, the spray would be attracted to the entire piece.

There IS an electrical charge involved and it WILL go all over the piece that is why you need to mask off when you do the seperate colors. Also, You will need to mask off for the black, coat it, bake it, let it cool, unmask it, reverse mask it, coat with the silver, bake the silver then let it cool and unmask. You cannot coat and bake both colors at once if you want sharp lines. The bicycle pictured above could be done at one time because of the fade. It didn't matter as much if one color invaded the others space. You will need to leave the masking on while the pieces back as the powder does have a tendency to float during the start baking process.
