This is spray painted plugs and light switches. Tape off around the plate and just spray. The brown plastic at the bottom is before and the textured metal looking one is after. I've had these like this for many years and no chipping. I used the hammered metal spray paint by Rustoleum you can get at Home Depot or Lowes. The color is either dark bronze or brown.
After - Plug
After - light switch*
The light switch is an outdoor "cover" plate I picked up at Home Depot. These plugs are all on my island and there's an odd double switch that controls one overhead light and the garbage disposal in the sink. For fear that someone might accidentally hit the switch at a bad time, I decided to cover it to prevent it from accidentally happening. That switch plate was gray before I painted it, so you can see that the hammered metal paint really covers well.
