Having one of those days today; ladder blew over and left me stranded on a roof and last couple of jobs have left spots behind and have needed redoing which got me thinking about PPM. I've read anything up to 010 is fine for window cleaning and Unger recommend I change my resin once it reaches this level. I normally go to about 006/007 before I change it but what do you guys recommend as acceptable?
