Ain't patina on the surface. That's case color hardening, an alchemic technique in creating a glass-hard, high-carbon protective surface on low-carbon steel, commonly used on firearms at the time and is still used today. The rainbow of colors is just a byproduct and is often simulated cheaply using chemical etching. On non-ferrous materials, it can only be done through a laborious paintjob with air brushing and wet sanding. However I've a cheap way of simulating it with spray paint using several layers of base color paints (silver,gold,black optional red and blue) half dried then swirled around with a thinner soaked cotton ball. Shown below in my half-assed attempt without dry brushing all the grime and accents yet.
Hey I am interested in getting my hands on one of your cast I could I please have one painted with working leds please and how much thank youHey I've been building a screen accurate blaster in 3D and am looking at having it 3D printed. I was wondering if anyone else would be interested in purchasing a cast and what size their wrist and forearm is? Also, would you want a fully painted cast with working LEDs and HUD? Or just a raw cast for you to paint and finish yourself? PM me with all the fun details and I'll see what I can get going...
