Get a Snow Foam result without an expensive pressure washer With the Eclipse Premium Foaming Spray Gun you do away with the need for a pressure washer and just connect your garden hose, add some car wash or snow foam formula and spray away. The 900ml capacity allows you to get a good mix of water and detergent into the reservoir and should be enough to cover a large car, ute or van. The Premium Foaming Spray Gun is the initial stage for getting a brilliantly clean car while preventing the scratching process that can come with poor preparation, like using a sponge on dirt and road grime sitting on the paint surface. With the Spray Gun you're agitating the dirt, lifting it off the car's paint and preventing scratches that inevitably occur.
