Put a piece of paper towel over the logo, and then soak it with one of the solvents. Let it sit overnight. /ubbthreads/images/graemlins/sleepy.gif The paper towel will keep the solvent in contact with the logo, and prevent all of it from running off. I would try the fingernail polish remover or the brake fluid. Don't use oven cleaner for sure, it will consume the aluminum. It may be that it will work over time, but not right away. (Just for the education, you could spray some oven cleaner on a piece of aluminum foil, crumple it up, and sit back and watch.)
I bet Skydrol would take that off. I haven't seen a paint yet, that could withstand the destructive power of Skydrol. Does anyone have access to some that could they could send him in a small glass bottle?
Oh, Skydrol is the hydraulic fluid used in most airliners, because it is fire-retardant. It is a purple liquid, has a stinky chemical smell, and burns like hell if you get it in your eyes, or any sensitive skin.
Skydrol bubbles up polyurethane paint, and DuPont Imeron paint and primer, down to the base metal with ease, over a little time.
I am going to try this same thing with a Marlboro Minimag. It is the silver one with the red lizard on it. I'm gonna try to get that lizard off, and the light has no knurling on the barrel at all. If it works, it will look cool, and be one of a kind, like the nascar light.
I don't think the logos are laser etched, or it seems that they would be slightly recessed into the aluminum, like the Mag logo on the head is. I think it's just decent paint.
Now as for the stripper jacking-up the anodized finish, I really dont know. I was considering on the Minimag I'm going to do, immersing the whole light (sans parts) in a solvent for a day, hoping that any effects on the base finish, if there were any, would appear uniform at least.
