Using Masking Tape

Scotch-Blue Painter's Tape for Corners and Hinges (#2090CM) comes in handy precut, medium-adhesion shapes that you peel off and stick to window panes, hinge leaves, and other tight spots. They won't lift paint that has cured at least 30 days, and they'll pull up clean—and survive in the sun—for up to 14 days. About $5, 3M
