Default Remove color from an anodized spinner?

I purchased an anodized spinner for my World Models GS Zero however the spinner has a spiral stripe and color I would like to eliminate.
Anyone know if it possible to get the spinner back to bare metal color so it can be repainted?

I just did one, used 400 grit wet paper and remove the finish. I then polished the spinner on a wheel and I left it that way. It looks about as good as you could ever hope to achieve ! Guess I could spoil it with paint?

Oven cleaner will also remove the anodizing. Don't leave it on to long though.

I tried the suggested method of using oven cleaner to remove the anodized coloring. This actually worked really well; I soaked the spinner and back plate then let them sit for about an hour.
The ended up with a black crust on them; all I had to do was use my dremel with a wire wheel and knock off the crust and I was down to bare metal. Worked like a dream and using the dremel
to take off the black crust did not take very long at all.

I have one of Frank Tiano's out of print color chip books (Great resource...wish he would print more of these!), compared my photo of a spinner on a full scale and got as close as I could with
an off the shelf rattle can. I used Valspar Paint + Primer and chose the color that was as close as I could get which was a bout 2 shades off the color of my full scale source. However I do not
think 99% of the people who will see this will never even be able to tell that the color is just a bit off. Once the paint dries I will give it a shot of automotive clear coat and it should be good to go!

"I have one of Frank Tiano's out of print color chip books"

Two things to remember about published colors. Printed colors do not accurately reproduce the oil/dope/pigment because printers ink is not the same.

Color chips, if actually painted, have the same problem as real paint; they oxidize, and change color over time.

Hi Les,

You are right on the button with that; unfortunately all of this stuff is subject to individual interpretation and you have to have a starting point.
This plane will never be a contest plane... I will over time add details here and there to dress it up a bit and keep it interesting. Getting the
exact spinner color was not really my goal on this one; I just wanted to get close enough to make me happy with the look of it
