Invisible Shield PRO 15 Nano Glass Protector in practice: test after 6 months without maintenance

We tested the Invisible Shield PRO 15 nano glass protection paint in real outdoor conditions for 6 months without a single cleaning. What is the difference between treated and untreated glass?

Check out the test results, which clearly show how the right glass protection can make it much easier to maintain and keep your glass clear even under long-term load.

How the test worked

The test was carried out on two glass samples:

- one glass was treated with Invisible Shield PRO 15 nano protective lacquer,

- the other glass was left without any protection.

Both samples were exposed to identical weather conditions for six months without cleaning. The aim was to objectively assess the effectiveness of the glass protection in real operation.

Test results

Untreated glass:

- Significant soiling

- deposits and reduced transparency

- overall dingy appearance requiring maintenance

Glass treated with Invisible Shield PRO 15 nano lacquer:

- significantly improved clarity

- minimum deposits

- cleaner and visually lighter appearance

- less dirt build-up

The difference between the individual samples is already apparent at first glance, especially when comparing dirty and protected surfaces directly.

Conclusion

The test confirms that the Invisible Shield PRO 15 nano glass protectant effectively reduces dirt adhesion, facilitates maintenance and helps to keep glass in better visual and functional condition in the long term.
