Rescuing an unfinished HA 2C

I've adopted a Mag 2C that someone was building but stopped before it was finished. I can replace the dried out gaskets and such easy enough, but the metal itself is another story. It appears the parts were stripped and HAIII coated, but the electrical contact areas were not masked or 'cleaned' afterword. I've worked with type II before, but I'm new to type III.

Short of chemical treatments or taking it to a shop, what is the best way to remove the extra HA? I'm thinking brute force, power and hand tools.

Thanks,

EG, the short story is that you can use any lye-based agent to remove anodizing (any type).

Depending on the concentration of the product you may need to dilute it a bit and play with the stripping time.

Also, use eye protection, gloves, apron (or old clothes) and work in a well ventilated area.

Here's the mother of all anodizing removal threads since you like investigating things.

I have used a wire brush with a dremel to remove type II anodizing
maybe that will work on type III

It does, but it takes a bit longer.

I don't mind the time if it gets me there. Are we talking nylon bristles or metal?

Metal. I've never tried it with a metal brush, but I'd start with a brass brush.
