I got a Wagtail a few weeks back and was just about mastering it after a few modifications.
Now before i go on i know it is my fault for altering the Wagtail but it might be useful advice for anyone else doing what i did.
I found the rubber supplied with the Wagtail too hard so replaced it with some favourite soft pulex and also dog eared the channel ends, there are no end clips on the rubber as it is held in place by a centre screw.
This morning doing one of my regular shop cleans i heard the unmistakable screech of sharp metal on glass and the sickening sight of a bad scratch on the glass.
What had happened was the rubber had pulled clear of the dog ear and the channel end had scored the glass,tried rubbing it out but it is scratched and a pretty bad one at that.
No-one in the shop at the time but i am back next week to face the music while the Wagtail lurks somewhere in the bowels of the van discarded and in disgrace.
Anyone had this problem before ? i am just glad this never happened on a domestic job as i found the Wagtail handy for cleaning dormer windows off the ladder with a pole .
In time i may dig it back out and see if i can fit some end clips or a brass channel onto it.

Sorry to hear that mate cant be a nice feeling, This is why I only use brass channels,

Yes, the alloy channel is a serious glass scratcher!!! you would think wagtail would smooth the end off after it has been cut to length. :

What I have done is, with a very fine tool, file all round the edges of each end of the channel. Round all angles off so no sharp edges are left. This stops it from scratching the glass. Keep inspecting it though as it can soon wear a sharp edge back.

for sure i will be filing the ends after reading this. i was planning on loosening up the middle bit of my yellow wagtails to make changing the rubber easier but wont be now,after reading above what can happen . Still using wagtail only here

Careful dog earing them too. I tried to dog ear my new whirlwind and simply cracked the aluminium.

I think the rubber in the Wagtail is magic.  It seems to last forever.  Why didn't you like it?

Found it too hard and was getting kicks on the turn of the sweep if you know what i mean.
I don't want to slag off the wagtail as i think it is a useful tool for certain jobs but after this morning i would be happier with an end clip to hold the rubber in place rather than exposing the channel.
I only use one clip on my brass channels after a tip on these boards a while ago and never had this problem before.
