There have been a few times or posts recently where these guys had a chance to prove themselves and all they
had to do was recommend their own product.
One was a guy having problems with bird poo the other was a guy with spotting problems and each time they remained silent.
I tried both Vision and GG4 on problem openers and both products made no difference to the problem, I tried it on my own
windows just to see if the shine improved and I seen no difference other than they did look slightly shinier when wet.
Just to see if I was being over critical I cleaned one window with both additives and one without and then asked a few people
could they notice anything about both windows, none could.
As for glide, I use an Xtreme brush so I couldn't notice any difference in the glide again on both products.
I don't really have a problem with spotting other than the problem openers already mentioned so cant comment on this.
So would I recommend this product well I'm sure there's no surprise when I say no.
I honestly cant see any reason why somebody who's knows what their doing would find this product in any way useful.
