The new steam gun makes the steam car wash easier since, controling the steam with its trigger instead of the traditional on/off switch is much more efficient. Also, the soap injection is more accurate by using the red button on the gun. We have designed a special metal end nozzle tip for the gun, with a rubber protection, in case the gun nozzle touches the user's skin accidentally. We recommend the use of this professional steam gun, it is compatible with any IMEX-SC05.
