Hi All, Can anyone PLEASE tell me what the history/ evolution/ progression of the 3M "quick clean" spray gun is? I tried to Wikipedia on the subject however I cannot find the answer. I am very interested in the "quick clean" features of this type of system and I want to buy a starter kit however I do not want to get locked in to an out of date model so if you all have any recommendations as to what model to buy I would really like to hear your thoughts. I am just a home hobbyist so the obstacle to me getting a compressor based spray gun has always been the long clean up for a traditional spray gun for a small job however...IF...this device is easy to clean and easy to use I would really like to jump in to a more professional and longer lasting paint coating than the traditional rattle can jobs that I have done in the past. THANKS for the advice!!!
