So been giving my new WFP system a run in today. Only took a couple of drums out, so decided to use the remaining pure water in my bucket. By christ, works like a dream! Barely have to detail. Literally just had a dash of ecover lemon in it and that was all. Built my whole technique around detailing efficiently to get those f*cking soap/hard-water smears off, but none of that here! Heartily recommended, deffo saves time even without a pole. And scrim use. Bit sad of me to write a thread about it but hell, sharing is caring!
