Here you will see it is not necessary to dog-ear your squeegee channels inwards but just up!!
 This can be done with any standard squeegee channel.
 This will explain why.

In the video you will notice when flexing the squeegee rubber back .
Goes back on the squeegee channel.
However cutting and splaying the channel up closer to the edge of the squeegee rubber.
That that part now does not flex that far back.
There is no need to press hard on the squeegee.

  Thought I did
You mean the tiles set at the bottom of window??
Although most of time I don't in the videos.
It was just to show how we used the squeegee.

OK now also have done this to Liquidator Steccone and Wagtail channels.
Wide body channels like Sorbo in the video above.
Plus here is once you have done this to your channel;
There is no need to adjust anything will not fall off it’s not an attachment.
No need to change the way you use the squeegee.
They all work as good if no better then other ideas out there.
