Glass coatings are definitely something that would be useful to most drivers. Especially in the poor weather conditions we experience in the UK.
Glass coatings improve visibility by repelling water, traffic film and dirt. What this means is that your windscreen stays cleaner for longer, giving better visibility.
In rainy conditions I’m sure most have you have experienced poor visibility. Water pooling up on your windscreen and wipers not helping at all. This can be solved with a glass coating.
The water behaves drastically differently, it will bead up and fall right off, meaning at some speeds you may not have to use your wipers at all.
Having a glass coating mean that a clear, streak free finish is a lot easier to achieve with glass cleaners, this is due to water repellent properties.
