I'm also a SW 2.0 fan and love that rusted look on a pair of Wires !! Great idea and as far as I know you're the first to try it ! How did you prep the frame surface and what paint did you use ?? Or did you mix some Cerakote ??
It's basically paint, that I add really fine iron to, after surface prep, paint the frames, alow to dry, treat chemically to cause it to rust, once I get the desired amount of rust, I then treat with a chemical to stop the rusting process
