A low voltage, portable, outdoor spray system for applying sunscreen to a user. The system is comprised of a booth having a floor and at least one wall defining an enclosure. At least one spray nozzle is positioned within the enclosure and is connected to a pump. The pump in turn is connected to a reservoir tank, which may hold a sunscreen lotion, a tanning lotion or a aloe vera lotion. The spray system also includes an automated payment system. Once payment has been verified, a microcontroller sends a signal to the pump to begin operation. The pump draws lotion from the reservoir tank and delivers the lotion to a check valve. Upon reaching a predetermined pressure, the check valve opens and releases the lotion through the spray nozzle and onto the user.
