I live in the Central Coast in California. I used Powder Coating USA in Paso Robles, CA. They did a really good job, considering I gave them a used and abused flashlight body.
I'll get some pictures put up tomorrow
l disassembled and had the exterior of my flashlight powder coated. Now that it is re-assembled, it won't turn on. I'm using an md20x lamp module, which I verified worked in other flashlights. It has a new battery and a new switch.
Maybe the new battery is dead? I charged it for 10 hours...
