Abstract
Masking tape is disclosed for covering the gaps between adjacent panels of an automobile body and for isolating a section of a panel to be refinished. The tape includes an elongated flexible core having a cross-sectional shape of substantial thickness. At least a portion of the core's outer surface is adhesive. The core is narrow enough at one end to be inserted into a gap and wide enough in another portion to cover the gap, but not the panel edges. The outer surface of the core is angled or curved in such a way as to form an outwardly opening pocket which creates a vortex during spray painting which, in turn, causes paint to gradually diminish in thickness or feather out in the direction of the pocket's bottom.
Claims3
A method of spray painting objects having a first section to be spray painted and a contiguous second section to be masked, at least a portion of the intersection of the first and second sections being along a horizontal curve, said method comprising:
- providing a masking tape including:
- an elongated core having an outer surface and a cross-sectional shape of substantial thickness, said core being flexible along its length so that it is capable of following horizontal and vertical curves, the core defining a first portion of the core's outer surface that diverges away from the first section of a object to be painted when the second portion of the core's outer surface is adhered to the object's surface;
- and
- means for adhering at least the second portion of the core's outer surface to the object's surface;
- masking the contiguous second section to prevent paint from contacting the second section;
- applying at least the second portion of the masking tape along the horizontally curved portion of the intersection of the first and second sections of the object to be painted to form a pocket opening outwardly from the intersection of the sections over the first section to be painted;
- and
- spraying paint on the first section of the object so that the paint encounters a vortex at the pocket which causes the paint to diminish in thickness inwardly terminating at the intersection of the first and second sections.
