Abstract
A self-adjusting masking plug is provided which is adapted to be received in a region of a complex part intended to be masked. The plug has a body adapted to be received within a region of the part intended to be masked. The body includes a first body half having at least one first perimeter wall conforming to a first portion of the intended region to be masked; a second body half having at least one second perimeter wall conforming to a second portion of the intended region to be masked; and a wishbone spring formed internally within the body such that it interconnects the first and second body halves. The wishbone spring includes a first half inner wall transversely spanning and interconnecting portions of the at least one first perimeter wall; a second half inner wall transversely spanning and interconnecting portions of the at least one second perimeter wall; and a common rib interconnecting the first and second inner walls. The plug is adapted to expand or compress depending on the tolerances of the part within the part.
