You could strip off the anodizing.
It won’t be quite the same as raw, but still looks pretty good. If you want it to look shiny afterwards, you’ll need to polish up the bare aluminum.
- If you remove the anodizing without disassembling the light, the internal parts will hopefully stay anodized maintaining tailcap lockout.
- WARNING: before attempting to chemically remove the anodizing be aware that:
- If some alkaline fluid gets into the cracks and degrades the anodizing around the edges of the contact tubes in the body, it might render the light non-functional by causing a short.
- Removing the anodizing might make the minimal knurling on the body tube a bit slippery.
- Bare aluminum scratches very easily.
- Fortunately, the scratches can be pretty easily buffed off with metal polish or a Sunshine polishing cloth.
- There is a thin plastic coating you can apply to help protect bare aluminum if you find the scratches too much to deal with.
