I have just opened a new packet of ten Unger hard rubbers to cut off a few ready to use. My main squeegee is a twelve inch Liquidator, exactly, as it is cut down. So if I'm careful I can get three off a '36' inch with about an inch and a half left over, however, today when it came to the third one I was about 4mm short. So I think Unger are cutting back a little. The thing is, do I use a 42 inch and have six inches left over, or would it make sense to knock half an inch off my squeegee? There's a conundrum..
