A method for preventing the deposition of material in an opening near a surface of an article, and a masking insert therefore. The method and insert are particularly suited for preventing the plating of a metal, such as platinum, on turbine airfoils or turbine blades and vanes having a complex geometry, as is the case when cast trailing edge cooling slots are present in the airfoil surface. The method entails the use of the masking insert, which is precisely configured to mask the cooling slots during plating by preventing circulation of the plating bath through the slots. For this purpose, the insert is equipped with appendages that are sized, shaped, spaced and oriented on a base member to register with, and preferably be received within, the cooling slots of an airfoil having a particular cooling slot design.
