I was able to finally get a commission done!
Vallejo Surface Primer (White and Black)
Vallejo Game Air
Citadel Layer Paints
Citadel Shades (Nuln Oil for metal, Agrax Earthshade for reds/oranges)
I was able to match the color of the SS Walsh by layering multiple thin coats of Vallejo Red and Orange, and dusting it off with almost a candy coat of Yellow.
Hopefully my next write up will be more detailed, but with the coffee shop opening up next month... Time will tell. :)
