Shocking experience. I was suggested to buy refurbished Q -Tech paint spray machine Q-P025. £200 cheaper than a new one I was told. In fact that was just £90 cheaper than a new one in Dulux Decorator Centre. "Paint Spray Tools" technician has showed how to use the machine, said no lubricate needed for that machine as it is so advanced. If I would want I could do oil once a week as this would not harm the machine. Cleaning of the machine was showed as to remove main filter cover and start the machine, let water out to run all directions ! The instruction DVD was taken off my hands saying that I do not need it as it will confuse me. I was told that I do not need to worry if paint is old and has got some flakes or loose dry bits as the machine has got so many filters that it would not harm packing. The machine was faulty and sprayed clouds of paint instead of steady flow of paint. After first spray all floor was covered with thick layer of paint. Spraying took ages and was making sand paper like surface everywhere. The front of the machine was getting very hot. The technician suggested to experiment as he did not know the reason for that problem. He gave other spray nozzle which made very little difference. We were suggested do not thin down the paint, change small grade filters to big ones to make paint go free through the system. When visiting the workshop again, the main filter was removed completely and not given back. We also were told that we are too fussy and wasting expensive time. So £10 cash was paid to keep technician happy. Though technician was saying that he would do service for cash much cheaper. We had impression that he wanted to ruin the machine completely so he could do services for cash. The machine was brought back and a new one Q -tech Q-P025 was purchased from Dulux Decorator Centre, Milton Keynes. Dulux sales assistant said immediately what was the problem with that refurbished machine. "Paint spray Tools " may call for advice from Dulux in Milton Keynes as they are trained by Graco and seems to know much more about spray machines . There was just one thing I have improved on Q-tech : that was change of spray nozzle to old one from old Titan 440 i. Which made Q -tech a superb spray machine.
