Painting Vent Windows???

[Kafer_Mike]

I pulled the vent windows out of the doors of my '69 Beetle last night and removed all the felt/rubber seals. I'd like to paint the window frames black. Can they be powder coated? If yes, I'd assume I need to remove the glass to do it due to the heat required for curing. What about simply using standard "bumper black" rattle can paint? Anyone done either method???
