Getting somewhere for elastomeric respirator style ! #steampunk vibe but P3 protection based on GVS Elipse P3. Now the right color elastics. Thanks to @nickelpin
for inspiration, paint advice. Angelus paint and finish, Games W. acrylics for deco. #Elastomeric, #respirator

A short description of the process. You can find a few pictures here, but I had some trial and error process and even with the final ones, no warranty it will hold long, as @nickelpin also explained very well !

So, take the mask appart, clean the parts well (I used dishsoap and then isopropanol after drying).
For the flexible parts (edges of the filters and facepiece) just paint the whole carefully with black Angelus paint. I used two fine layers.

You will have to paint each filter when you replace them. I have not painted the parts that make the contact between filters and facepiece to avoid to make air entries. Even so, I am not sure it is as good as before for seal.

The plastic part has been sprayed with plastic primer (one from acrylics Vallejo for miniatures, but probably many other brands would do). Use black, covering the red was not fun. I painted over it with black acrylic (Black from Semple as I had it at hand and it is non toxic)

I then added gold highlights (mostly finger painted for the surfaces, so it would be irregular, plus a bit with a fine brush). I added a red wash on some areas. The "nails" were added after the wash with a dot tool (a little metal ball of 1 mm on a pen) and enough paint to 3D.

Same for the dots on the facepiece. If you do not clean the tool the dots get progressively bigger. I finished with a layer of matte Angelus finisher on both. Apart from the Angelus paint, I think the others can be replaced by other brands.

The paints used, and the tool. Sorry, I was mistaken on the golden acrylics and wash, not GW but (cheaper) Acrylicos Vallejos too.
The tool is nail art originally, but a toothpick can probably also be used...

After almost two month, worn something like 5h a week for high density public transportation. Washed cleaned inside after each wear, weekly deep clean with soap and water. Paint is mostly ok, with a few spots where it is starting to peel. Should have sanded hard plastic.
