Since the DIY seventies, home improvers have used Plasti Dip rubber coating to give their tools better grip, prevent rope from fraying, reseal dishwasher racks, and even detail their cars. Basic colors sufficed back then, but in today’s post-Etsy world, the demand for additional hues is greater. Enter Plasti Dip’s Create Your Color kit ($20 at Rainbow Ace Hardware, 1449 First Ave., nr. E. 76th St.; 212-517-7500), which allows you to customize shades by combining clear Plasti-Dip with yellow, red, blue, black, or white tints. From there, what you dunk—scissors, spatulas, the tips of your brogues—is limited only by your imagination.
