Removing HA3

[4sevens]

Hi.. I'm trying to remove the HA3 on an infinity/gerber ultra so it's
plain aluminum. But I'm having a really hard time doing it.
I'm using jeweler's polish and it polishes up the HA to a shiny
silky gloss, however, I can't get to the aluminum yet.

Should I just get some rough sandpaper or a file and work on it?
Will HA3 break my file?

Caustic soda/Red devil lye is what you need. Mix up a weak solution and drop in the part you want to strip. Keep checking every few minutes by scrubbing with a wire brush or similar, the HA coat will eventually come right off.

You need to keep a close eye on it though, if left in too long it will eat right into the aluminium itself and cause pitting.

Lye will work fine for the battery tube, but it will probably destroy any components in the head.

I need something to remove the HA on only the reflector.
My attempts at sanding it down have turned bad. It looks horrible
with some aluminum showing up but still with a nasty green
tint.
