Put a WD-40 Smart Straw Cap on a Spray Paint Can for Two Spray Modes
The flip-straw cap from a WD-40 can fits a standard spray paint can. Straw down, you get a wide, comfortable spray with the nozzle out in front of your fingers; straw up, you get a precision stream that reaches into tight spots. Return the cap to the WD-40 can and a couple of bursts self-clean it.
