Even with a laser to speed the process, the time spent really adds up, but with a good setup you can work inside while relaxing in a comfy chair.

I finally decided to cover panels with tape before etching and filling the framing pattern. At least it kept the gook out of the pores, but then you loose that "antiquing". Still had to sand so removing the tape wouldn't pull out the fill, but made it fun to see the panel get exposed. Just like opening a gift.
