1. A method, comprising:
(a) moving a footprint of an applicator wheel through a supply of sealant to load the footprint with a charge of sealant;
wherein the footprint comprises a backstop positioned at a trailing end of the footprint;

(b) moving a web of shingle stock in a horizontal direction;
wherein the applicator wheel is configured to rotate along an axis perpendicular to the horizontal direction of the moving web of shingle stock;
wherein the web of shingle stock has a first surface and a second surface opposite the first surface;

(c) moving the footprint and the charge of sealant loaded into the footprint toward the first surface of the moving web of shingle stock;
(d) as the footprint and the charge of sealant move toward the first surface of the moving web of shingle stock, inhibiting the charge of sealant from being displaced from the trailing end of the footprint as a result of the movement of the footprint from the supply of sealant toward the first surface of the moving web of shingle stock with the backstop;
(e) transferring the charge of sealant from the footprint of the applicator wheel to the first surface of the moving web of shingle stock;
wherein during transfer of the charge of sealant to the first surface of the moving web of shingle stock from the footprint of the applicator wheel, areas of the second surface of the moving web of shingle stock directly opposite points of transfer between the footprint and the first surface of the moving web of shingle stock remain exposed to an external environment;
and
(f) repeating steps (a) through (e) to apply a strip of sealant characterized by sealant dashes separated by spaces along the moving web of shingle stock.
