They key to this product is preparation! You need to clean the glass properly first. I used a glass polish (Ceriglass) with a Rayon Glass Polishing pad on a machine polisher. Then used Isopropyl to remove any residue. Three coats of G1 on the windscreen and one on the rest of the glass. Leave 5 mins between coats, then you can use the supplied remover but they don't give you enough, so just use Isopropyl again and also use it to clean the wipers. In fact, I am pretty sure that's what's in the bottle anyway. Make sure you do all this on a warm, overcast and dry day or undercover. Do not apply in direct sunlight. Do not allow it to get wet for 24 hours. Once cured it lasts at least 2 years, well it does when I apply it. Zero judder on wipers. It's great when done properly - water just fly's off the glass. You don't even need wipers at times and your glass is less prone to frost and bugs don't stick to it so well. I've used this on four cars now, with the only issues on the first car and that was my fault for not cleaning the glass well enough first. Lesson learnt. Anyone having issues, it's you, not the product.

Great product, apply as directed, beads water crystal clear windshield.

At first I was not impressed. It took a considerable amount of work to apply. And it rained within days of applying, and unless I was going 50+ mph it did not work very well. Well, wait a week or two and it cured fully? Or it polished? I don't know, but wow! It's been over a month now and this stuff works great. Hardly need wipers at all. Very impressed! Hopefully it lasts the 6 months or so that they state it does.
