Powder coating sprocket

My sprocket on my bonanza is painted.I am getting some things together to powder coat and was wondering if doing the main sprocket has any issues with the brake.Should they even be pained.It looks like they come zinc plated new.
I would think powdercoating it would make it to thick for the chain, and it may not sit right in the teeth.. and if it's also used as a disc brake it may make it to slick to grip..
You can powdercoat the sprocket with no problems ... Just be sure your guy tapes off the inner part of the brake drum and you'll be fine
