Reasonable method of cleaning, although Id say your corner-work will leave an unacceptable state of affairs. Interesting you didn't do the narrow side panels and we haven't seen you do anything above 6'. Ive always thought that all you do is bodge up something that is already on the market as if its something new. Ive never seen you bring anything to the market that is unique or rather unique and worth pursuing.
That's about et.
Can assure you most of the windows were 6 feet or more.
Could you squeegee like that on smaller windows using a large squeegee?
If so put a video up .
No that is also true, never brought anything to the market.
But have had some manufacture see some of the videos that we put up and emulated our ideas.
And one is now on the market.
Can call it bodge, we call it modification to improve the tool so the make it work easier.
