A few weeks ago I got some rain repellent and applied it as instructed
to all the windows.

http://www.gbdriver.co.uk/acatalog/Car_Care.html

This stuff is a 'glass treatment' and allegedly bonds to the glass,
although I had no idea of this at the time. Well it kind of does work
but the effect isn't all it seems. Previously at low rain volume,
intermittent wipers would keep the windscreen clear. Now at low rain
volume, the slightest amount of rain sticks to the windscreen and
quickly reduces visibility. Intermittent wipers are not quick enough
to
clear it.

Worse, since applying a couple of times, the coating has become very
patchy. Much of it has worn off, which is actually good because I do
not intend to reapply it. The problem is that when I use the wipers
now, every time the wiper swipes over the remaining patches they
momentarily become smeared, before 'fading' back to transparency. Then
the wipers go back down and the same happens again. When there is no
rain or the wipers are not used, the stuff stays invisible.

Most of the remaining patches are in the drivers swept area of the
windscreen, and while not MOT-threatening, they are really annoying
when
it rains. I like to have a clear windscreen. I've tried using hot
water and detergent and that's had zero effect. It does seem to be
wearing off very slowly anyway (hence the need to reapply the stuff
every few weeks).

I read an article today which mentions this smearing effect.

Anyone know how to remove this kind of stuff from the windscreen? I
did
a groups search and found someone talking about this stuff about 10
years ago but they were explaining how to clean the windows before
application in order to get a good coating.
Halfords do (or used to) a glass cleaner they called "Intensive Glass
Cutter" I think (It's at the garage so I can't be bothered to go look up
the exact name) and I find it makes a fantastic job of getting virtually
anything off the windows of my cars. The only thing is as it fogs up
when you put it on you can see every imperfection in the glass.

Neat Alcohol (well 99.9%) buy from chemists. Or you try jewlers rougue if
you can get hold of it.

Jewellers rouge is slightly abrasive though isn't it? Will that be
detrimental or is it mild enough to be OK?

It's very very mild, you can use it on windscreens no problem, if your still
sceptical try a bit up the corner first.

Peter.

Best wishes all,
Dave.
