I think I've heard that oven cleaner strips off ano... you'd have a cool silver tube with black ends...
So does degreaser i used to use if for stripping anno of RC parts
Is there something that will remove only the logos? I don't think they are laser engraved so some kind of chemical should be able to remove it.
When I hit a few of my lights with a blow torch the printing was not affected so I doubt you will remove it without damaging the ano.
Use the $5 to buy some grip tape, cut to cover the flat slot on both sides. You will then have a custom modded light.
