When I am hand polishing edges of floors I sometimes spend 2 0r 3 days on my knees. I wear snickers floorlayers with the expensive silver snickers kneepad inserts. They are brilliant. I used to wear the middle of the road pads also from snickers but their silver ones are better again. So what they cost about £85 total with the trousers. Cheap price for comfort all day long and intact knees.
Oh well its off to work for a day of polishing for me
