The chemical bond between the silane and glass is the reason that the

Which is what made me think this Vistec coating may well be very
similar, the description certainly is. A kit of RainX cleaner and
solution is probably a lot cheaper than this coated glass. You will
need some elbow grease and time though.

I was always suspicious of the claims for RainX until they had the
kit in CostCo for about £8. What the hell I thought I hate smeary
windscreens so bought it and applied. Very impressed, it does wear
where the wipers wipe in a couple of years but the second
clean/application is easier than the first.

Thanks for the replies guys. The only reason I allowed the salesman in was
that they reckon that you can now get a government grant for it. We live in
a "standard" 1960's 3-bed semi-detached dormer (chalet) bungalow and the
window coating would be £2,500GBP without a grant or £1,500GBP with a
grant!!!!!

Needless to say, I didn't take up the offer - £1,500 pays for a lot of
window cleaner man-hours )
