There are a few things you need in order to make a foam gun for car wash. The most important part is the foam gun itself. This is what will help you clean your car in record time. You will also need some supplies such as an air compressor, foam gun, and water. The first step is to find the right size of foam gun for your needs. Make sure that the gun is able to shoot a large amount of foam at once. You should also be sure that the gun can be easily cleaned. Next, you will need to find some water. Make sure that the water is cold and clear so that you can use it to shoot the foam. Once you have shot all of the foam, it is time to clean the gun and its components. Be careful not to damage any of the components or the gun itself.
