You should invest in waterless wash. You could do that, clay, and polish would using the hose at all. Just use a wash facility before hand if there is any real dirt. Or, park outside in a hurricane, that might remove the big stuff.\n\nDA is nice because it does the work for you, but you still need the compounds and pads to go with it. YOur technique will determine how well the DA works, and Ultimate compound is very forgiving and easy to use. It doesn't dry out, it doesn't need to break down (abrasives stay small, and can be worked faster\/harder to achieve greater cut), and it is cheap and easy to get your hands on.\n\nSheepStar\n\nI ordered a bottle of the ultimate compound. Seemed like a good place to start.
