Re: mill finish prep
Yes, I agree... etch step will ensure a uniform surface.
So... lacquer thinner to remove ink/grease/oil, etch, de-smut/de-ox, ano.
No need to de-grease after de-smut as long as the parts are not handled with bare hands, and they pass WB.
Etch solution: 1 can (16oz?) Red Devil lye into 3gal water (no more than 70F).
