Paint mask assemblies are described herein in various embodiments. A paint mask assembly includes a window portion having a removable mask affixed thereto. The paint mask assembly can be affixed over a mark on a surface so that the mark is visible through the window portion of the paint mask assembly. When the paint mask assembly is painted, the paint is applied over the removable mask, but the window portion remains unpainted. When the removable mask is removed, the mark remains visible through the window portion of the paint mask assembly.
