A wireless-operated anti-graffiti spray can system (10) which allows a pressurized spray can (162) to be electronically operated from a remote location. The system (10) is disclosed in two designs: in the first design, a spray can activating device (38) consisting of a solenoid/valve assembly (42), which operates in combination with an electromagnetic coil (40), is used to control the spray can (162). In the second design, the activating device (38) consists of an electro-mechanical solenoid (138), which operates an articulated spray control leaf (142) that is used to the control the spray can (162). In both designs, a transmitting unit (12) is utilized that can only be enabled when connected to a utility a-c power source (160). The transmitting unit (12) produces an RF signal that is received by a receiving unit (28) located remotely and adjacent to the spray can activating device (38). The receiving unit produces a power signal which, in the first design, causes the activating device (38) to produce a magnetic field, thus causing the solenoid/valve assembly (42) to be energized; in the second design the power signal is applied directly to the solenoid (138) which causes the solenoid (138) to be energized. In both designs the spray can can only be used after, either the solenoid/valve assembly (42), or the solenoid (138) has been energized.
