This kit is ideal for automotive applications like repainting car panels or motor bikes. The gravity feed design has a more efficient paint consumption rate and reduces occurrences of paint splutter when the paint runs low, giving a great finish. Cover large areas with the 1.4mm Gravity Feed Spray Gun, then create a perfect even finish by covering any inconsistencies with the touch up gun. The air regulator allows more accurate control of the air pressure entering the gun.
