Rain-x for pano roof?

There was an "episode" of one of the series of programs about things found in nature that we have been further developed to solve problems in industry on BBC2 in March all about it. It works on the rain repelling capablities of the wings of some giant butterfly only found in the Panamanian Jungle which would be unable to fly after a rain storm if it hadn't evolved this clever surface on it's wings..............

Had it on my porsche too.

i use it on my pano roof it only lasts about a month but it is good!

gTechniq G5 (after clean with G6 and polish with G4) works fantastically, but wears off after about 8 months. the ultimate would be G1 for longevity but expensive and would be hard work for the whole panoramic roof, G1 is designed for windscreens and survives the wipers, but I actually am not a fan of these things on the windscreen anyway as the water action itself can become distracting.

Rain-x would do but was poor compared to gTechniq products, having tried both.

Had my car protected with GTechniq. Can't recommend product enough. Water beads and just rolls off.    

One bottle of 15ml G1 can cover the roof & 3 coats on the wind screen. Treated mine 18 months ago & the water still beads the same. It's party trick is once you drive away, the water just flys of the roof straight onto the car behind
