Described is a filament-bearing masking tape extending longitudinally and formed from and including a filament and a base tape having a first edge and a second edge parallel to the first edge. The base tape includes a carrier having upper and lower sides and extending longitudinally with a first adhesive on the lower side having a first adhesive thickness, and a second adhesive having a second adhesive thickness greater than the first adhesive thickness on the upper side, and a release liner attached to the second adhesive. The filament extends longitudinally, parallel to the first edge of the base tape, closer to the first edge than to the second edge.
