Exactly how many mm do you bend the corners forward?Also how much rubber overlap do you leave or do you cut it flush with the end of the channel?
When you say cut the rubber at an angle what do you mean?

Hi Glen.

It's all about experimentation really. My corners are bent down about 2mm, only a slight bend. But that seems to work for me. My rubber extends the normal amount (my rubbers are pre-cut), I haven't trimmed them further and they are not cut at an angle - they are straight.

If you bend your squeegee corners in small amounts, it's easier to bend them back again if you're not happy with the result. I just made up a fresh bucket of GG3 and water at home, took out my pliers and played with it until I was able to squeegee the glass to a standard that didn't require detailing afterwards.

I hope that this helps a little.

In reallity,the `dog-earing` part is secondry to the `key` to the whole business.
It is experimentation yes,but the answer just simply lies in a very simple maths/equasion.
i.e. 10 millimeters divided by 4 millimeters and your left with 6 millimeters.The 4 `mill`
being the end of your rubber the 10 `mill` being the overall lenth of your `cut out`
If ya really want to start getting complicated and your doing old sash windows with
linseed oil putties ya `cut out` needs to be 15 millimeters (old half an inch) all your other
measurments being altered acordingly. Anyone one would  think that this was brain surgury,
but its like learning to drive a car.Ya do`nt think twice when ya`ve learned. It`s only really
on the long channels that `dog-earing` is neccessary anyway.Think about it.What pressure
is there on a squeegee channel 22 inch or longer??? At the end of the channel that is.
The Sorbo channel photos shown are an excellent channel,but work on a completly different
principle altogether for `detail free window cleaning`.

That last bit was dead right.
Try blading with a 6" channel and then an 18".
The 6" will leave less detailing because there is more pressure down the sides of the window and therefore more water removed.
 For this reason I tend to use a 10" channel for most windows, except really big windows eg shops and then I do the edges with a 6" or 10" channel and then the large middle area with an 18". It leaves little or no detailing.
