I claim the ornamental design for a staining and sealing brush head and cap combination, as shown and described.
FIG. 1 is a perspective view of a staining and sealing brush head, showing my new design;
FIG. 2 is an enlarged front elevational view thereof;
FIG. 3 is an enlarged rear elevational view thereof;
FIG. 4 is an enlarged right-side elevational view thereof, the left-side elevational view being a mirror image thereof;
FIG. 5 is an enlarged top plan view thereof; and,
FIG. 6 is an enlarged bottom plan view thereof.
The broken lines showing a bottle in FIG. 1 and elements on the bottom of the design in FIG. 6 depict environmental matter and form no part of the claimed design. The dash-dot-dash broken line in FIG. 6 represents the bounds of the claim and form no part of the claimed design.
