Enjoyed my Sichtschutzzaum including pergola and trellis (5m long, 2mhoch) painted with the PFS, time savings compared to conventional paint min 60%, moreover, I have less color consumed. With a little practice it works out really well, movements should be carried out smoothly otherwise there shades. (Max 5% dilution with water lt. Prod.) Was painted with an anti-fouling paint. Had to be diluted with about 10% in order to achieve a good result, because you mus stop experimenting. What I'm missing is a locking knob for the switch, which would have been helpful for the larger Fächen. Otherwise super device, cleaning is also unproblematic.
