Abstract
A masking system for an airfoil comprises a locator for positioning along the trailing edge of the airfoil, and first and second mask sections. The first mask section has a trailing edge portion with locator pins for cooperating with a positioning tab on the locator to position the first mask section along the trailing edge of the airfoil, and a leading edge portion for extending around the leading edge of the airfoil to locate the first mask section along the convex surface. The second mask section has a retainer portion for cooperating with a retainer process on the first mask section to retain the second mask along the leading edge of the airfoil, and a flange portion for extending between the locator pins to locate the second mask along the concave surface.
