It’s mildly gruesome, if very low-quality – fair warning – but here’s a page with a video of a unique use for the Black & Decker Mega Mouse (the one with the comfort gel pads on top) – sanding out an unwanted tattoo. The guy laying on the ground and having his left pectoralis major sanded to a vivid crimson seems unaffected by it, but also seems a little surprised when he sees it, stating “Wow, that s**t pulled me open pretty good.”
It looks like they’re using the finger plate attachment, seen in the lower right of this unrelated image to avoid sanding a much larger portion of his chest. Hopefully he didn’t end up with a bunch of grit embedded in his skin. Anyone know what you put on a reddened area like this when you’re done sanding? Shellac? A water based poly, perhaps?
