I'd like to hear some of the details about your electro etching process.

We considered this many years ago, but could never get it to work to the degree required. Using a secondary etch process in a production process at the time was not economically feasible as you would have to construct a completely new production line costing many $$$ as compared to the conveyorized spray systems then in use.
