The GRANT’S™ Extreme Foaming Spray Gun beats soaping your vehicle with a sponge and a bucket. The extreme foaming action applies a layer of soap to loosen and lift grime without brushing or scouring the vehicle’s finish. The extra large 32 oz. soap reservoir is translucent for an easy view of the soap remaining. The quick-disconnect pistol grip detaches from the reservoir for easy rinsing.
