Thank you.
Yes these are all etched using PnP blue and paint.
I've started to figure out the ins and outs of etching enclosures.
Most of my projects have been etched lately because the durability of the finish can't be beat!
I've got some more to post soon.

The technique is fantastic. Really nice resolution!
I intend to give photo sensitive laquer with subsequent etching a try. Worls on PCBs, why not on boxes.
Would you mind sharing your secrets ? 
Do you etch, paint and then sand until the excess paint is removed??

I usually will paint the sides of the box with a light coat of cheap flat black paint to protect the sides from etchant.
Then, wet-sand the top of the box, iron on the pnp pattern, then touch up areas where the pnp didn't quite adhere
as well as I like, then touch up the seem where the pnp top meets the flat black sides so that all that is left will be
exposed to the etch.
I then will wet sand the pnp/paint mask off of the enclosure, spray a nice coat of color onto the top of the box
to fill in the lettering and the wet sand a final time.
It seems tedious but, I must say that the time involved in preperation pays off at the end.
Also, there's not as much time watching paint dry......know what I mean
