Welcome to the forum.
Here are the directions from the product description page
Directions:
- Polish the glass
- Clean surface free of polishing oil residue with CarPro Eraser
- Pour a few drops over the supplied cotton pad
- Apply in circular motion in an organized pattern across the glass and do not wipe off. It will flash nearly invisible as you apply.
- On windshield: Repeat steps 3 and 4 (2 more times - 3 coats total) / On side windows skip this and move to next step
- Using the same applicator (but no additional Forte) once again repeat step 4 buffing off any trace of residue until the surface is 100% transparent and clear.
- For side windows only 1 layer is needed.
- Keep surface dry for 4 hours with no wiper blades for 24 hours.
I have included the products that will aid you in getting the best performance from the coating. You may also want to consider claying the glass prior to polishing.
FYI Ceriglass can be used by hand and does not always have to be used to remove scratches.
