Very true .............
Can't believe how many negative posts he gets about it

I use fairy liquid for my trad others use different stuff, am not exactly sure of price of a bottle of vision ( £15-20 ) but a bottle lasts quite a few full tanks so prob works out at pence per fill.
Am just getting started on this glass roof am doing, and I will be ordering some vision to help us
I am going to do a section with virosol and pure, with the section next to it using vision and pure, and I will send the pics to kempy and if he's happy he can post them
No guys, I don't know him from Adam so absolutely independent, but I did use the vision on all other work we done on this job previously, and the results spoke for themselves
