Abstract
A chemical attack polish and polishing procedure for use on metal surfaces such as nickel base alloys and stainless steels. The chemical attack polish comprises Fe(NO.sub.3).sub.3, concentrated CH.sub.3 COOH, concentrated H.sub.2 SO.sub.4 and H.sub.2 O. The polishing procedure includes saturating a polishing cloth with the chemical attack polish and submicron abrasive particles and buffing the metal surface.

A method of polishing a metal surface comprising:
- a. saturating a cloth with a chemical attack polish comprising Fe(NO.sub.3).sub.3, CH.sub.3 COOH (concentrated), H.sub.2 SO.sub.4 (concentrated) and H.sub.2 O;
- b. adding submicron particles of abrasive material to the saturated cloth;
- and
- c. buffing the metal surface with the saturated cloth for a time sufficient to produce a flat surface substantially free of microscratches and flowed metal.

A method of polishing a metal surface comprising:
- a. saturating a cloth with a chemical attack polish comprising about 3 to 7 gms Fe(NO.sub.3).sub.3 ;
- about 15 to 40 cc CH.sub.3 COOH (concentrated), about 3 to 7 cc of H.sub.2 SO.sub.4 (concentrated), and H.sub.2 O in an amount sufficient to form about a 400 cc solution,
- b. adding submicron particles of an abrasive material to the saturated cloth,
- c. buffing the metal surface with the saturated cloth for a period of time sufficient to produce a flat surface substantially free of microscratches and flowed metal.
