If you cant see the point, why ask the question.
2 people I know died falling off a ladder I dont intend to be no 3. It is safer and a bit faster. I lost work when I introduced squeegees into this area more years ago than I care to remember- "Is that it, what about giving them a polish" etc If you wait 10 years till most have a wfp then you will be one of the ones left to command the best prices and deserve it because you do it the old fashioned way, if you havent fallen off .The major manufacturers told me that its not for you it doesnt do domestic. Well it does and I have converted 97% to wfp the 3% dont worry me as I gained lots more bigger jobs because of the health and safety issues.
