I use a similar air compressor for the exact same use you are asking about , not only is it effective it is so much faster than any other method that I can find! It not only gets the water out but it dries it at the same time, no water marks, no runs, no drips, no errors. Extremely easy and fast, I have posted this reply to people who want to use a leaf blower, I have tried that also, but this is much better IMO because it can be directed in much tighter places ie" mirrors, grills, wheels, tires, jambs, hood edge, grills, trunk area, lisense plates, trim, glass edge, lugage rack areas, lights, and many more if you are using it you keep finding more and more!!!!!!!!!:buffing::hotrod2:
