Abstract: A method, and aqueous emulsion, for coating a metal part with a peelable mask that is resistant to attack by the strong acid and strong base etchants used in chemical milling are disclosed. The method comprises contacting a polyvalent metal cation salt-surfaced part with an anionic emulsion for a time period effective to coat the part. The anionic emulsion includes coalescent rubbery particles and pigment and has a total solids content of at least about 10 weight percent. The weight ratio of pigment to rubbery particles is about 0.1:1 to about 2:1, respectively.
