Worth the price. Best ive tried

Excellent durability and performance from G1. Hugely improves visibility in wet weather driving, wipers arent needed when above town speeds. I also found over winter that snow and ice is easier to scrape off your windscreen it doesnt seem to 'stick' as much. Amazing product and one that I will always have applied to all my car windows. Make sure your windscreen is spotlessly clean before application, I clay and polish mine first (using Gtechniq glass polish)

THE best, bar none

The best durability, high speed performance and pretty foolproof application method. I keep trying others, but revert to G1 every time!

How did i manage without this!

This is one of the best products I have come across in the last year. Gtechniq g1 is a durable rain repellent not only making wet weather driving safer but you don't need your wipers when driving over 50 mph in steady rain. Great to have in case of wiper failure. It can be a bit tricky to apply but give Ultimate Finish a call and they will help you out if you get stuck. Lasts over a year quick to apply once you know how. Amazing Stuff!
