I have a Tc15 that was getting prety scratched up. Ordinarily that's fine, but I wanted it to look nice as I have it on my belt all the time, even at church. I started by taking the anodizing off with oven cleaner, except for the threads, so I could still lock it out. I figured it would look like dull aluminum, but it actually turned chalky white/silver and the colour was not uniform. I tried sanding the body, but there was no way to get in all the grooves. I ended up using a burr bit in the dremel, and I roughed up most of the outside, and sanded the rest of it smooth. As the final step, I sharpie markered the entire flashlight and then wiped it off. The sharpie filled in all the cracks, and made a nice contrast to the bare aluminum.
I don't love how it turned out, but I think it looks decent. I can scratch it up all I want now, and the scratches will blend in almost completely.
Should I ever do this again, what are your tips for the process? Maybe I should sandblast it instead?
Before and after pictures, the anodizing was much more scratched before I decided to remove it.
