Systems and methods of applying self-seal strips of multiple different adhesives are disclosed. In one embodiment, two spaced apart spoked applicator wheel assemblies are positioned beneath a web of moving shingle stock such that each of the applicator wheels applies dots of different adhesives in an alternating pattern. In other embodiments, a layer of a second adhesive is deposited onto previously applied dots of a first adhesive to form layered adhesive dots with dual properties of both adhesives.

A pipe doping apparatus comprises a bucket assembly including a base and a bucket supported on the base and having an inside volume, a lubricating unit having at least one lubricant applicator inside the bucket; and a source of torque configured to rotate the bucket and/or the lubricating unit relative to a tubular. The apparatus may include a cleaning unit and/or a drying unit and the source of torque may be a fluid jet in either. At least one lubricant applicator may be retractable and may be actuated between a retracted position and an extended position by centripetal force. The apparatus may further include a positioning assembly supporting the base and the rotary bucket assembly and a controller connected to and controlling each of: the positioning assembly, the cleaning unit, the drying unit, and the lubricating unit.

A method of protecting a hole in a component during a coating process is disclosed. The method includes: placing a plug in the hole, the plug including a water insoluble core and a water soluble layer surrounding at least a portion of an outer surface of the metal core. A coating is applied over the plug and at least a portion of the component. The component is immersed in water to dissolve the water soluble layer, allowing removal of the water insoluble core. Removal of the coating from over the hole and the water insoluble core from within the hole may follow.
