Stop in for a cup of coffee

Talked to a guy last weekend. I want to repaint the dark argent on my Deluxe Chrome Wheel covers. He suggested using Cerakote paint. Its a paint they use on guns and gives a very hard finish.
I looked its expensive not sure if I want to hassle with that. Its not like these wheels will be abused. Think I'll just tape and spray.
Need to look through or start a thread in the body forum about the slightly darker finish on the taillight centers.
My guess is that's not paint?
