I had to remove the joystick which was a little complicated. After I got it off I stripped it with Aircraft stripper. Then I powder coated it with Epoxy Hammertone Black.
I cleaned/polished all the buttons. I used brake cleaner to clean up the joystick base.
Then I removed the old Cpo and put on the new one. Then I re-installed the buttons and joystick.

The extra button is a free play button. I debated removing it, but I kind of like it so I left it there.
