Need clarity. Are we talking about the top ring? As in beauty ring? Or the extension ring?
If it's the beauty ring. You're better off with a black derlin one from Loki Labs.
But regardless, I can share
through experience that paint won't hold up in the long run on SS. At best you can heat it in the oven and spray it with VHT engine enamel and it will last quite a while, but if it is handled a lot and subject to abuse, it will ding and scratch quickly.
Powder coat is a more durable option, but more costly.
