Primary Uses & When to Use It

Invisible Glass 91411 is designed for automotive glass care. Use it to:

• Prepare windshields before applying rain repellents or ceramic coatings so they adhere longer and perform better.

How to Use (Quick Guide)

1. Clean the glass with a standard glass cleaner to remove loose dirt.

3. Work the paste into the affected area using moderate pressure and circular motions until spots and deposits are reduced.
4. Wipe away residue with a clean microfiber towel and inspect. Repeat if necessary for stubborn spots.

Safety note: Does not remove etched-in damage. Always test on a small area first and follow manufacturer safety guidance.
