65 headlight bezel anodize hell

Trying to shine up my bezels. The one had some bad scratches in it so I soaked it in EZ-off for 15 minutes to strip the anodizing off and commenced to steel wooling the crap out of it to remove the anodizing. I thought I got it all off as it was all the same color after about 30 minutes of buffing it, then I took a flapper wheel to the scratches to knock them down. Turns out I got NONE of the anodizing off, and only the flapper wheel took it down to bare AL. How the heck do you get the anodizing off? I tried 2 different EZ-off formulas, both had sodium hydroxide listed (Lye) and another 30 minutes of soaking. Nothing, its not even coming off with 1200 sandpaper, but 60 sure did. I even tried black compound on a wheel. Nadda. That stuff is tough!
