I have some rings i bought for my friends that are stainless with the outer edges blue and the center a band of normal stainless steel. I was wondering if there was a good way to paint that center band their favorite colors. I plan on leaving the inside of the rings stainless in case they want to wear them. Most of the tutorials i found tell you to get the item powder coated but that's a bit much for 3 rings. Anyone have any ideas?
