A tape hub including a support portion defining a peripheral surface around an axis adapted to frictionally receive a cylindrical inner surface of a core wound with tape, and axially spaced radial projections and locating members on the tape hub for positioning a first edge of the length of tape wrapped around the core at either of two discrete tape edge positions axially with respect to the hub. The tape hub is useful on devices that adhere tape along one edge of masking material to afford selecting different amounts of overlap between the tape and the masking material. The tape hub can have a plurality of radially extending hub portions having spaces therebetween and axially extending ribs on the hub portions defining its peripheral surface with the peripheral surface being adapted to frictionally receive the cylindrical inner surface of cores of slightly different inner diameters.

A method for protecting a surface from radiant heat such as for protecting an outer surface portion of an automobile from heat during radiant heating to cure paint on another newly painted outer surface portion of the automobile. Exposed adhesive on tape along one edge of masking material comprising a polyester backing layer with a reflective aluminum coating on one surface is adhered to a surface with the masking material extending between the source of radiant heat and the portion of the surface to be protected from the radiant heat.
