Looking good. I have a question concerning the Rustoleum. The one time I used it, nongun related, I thought it etched the metal. This was on a large 4"+ diameter x 12" piece of hex stock. Have you had any problems with that? Do you dilute it? I haven't tried it on a gun because of that and formulas may have changed since that was in 1980.
I've use Rustoleum jelly in brush on and spray on containers, and not seen any etching. I've actually preferred it for stripping vs. sanding the old bluing off,as sanding removes more metal than chemical stripping. It saves me time, effort, and makes the final polishing much easier.
As you might see in the pics after, there is no etching I can see. The receivers I'v done come out slightly dull, as compared to the blued finish, but not etched at all.
If I'd gone after this bluing with emery paper I'd never have known there was any case colors left under it.
