How To Polish Car Glass

Remove grit, fallout & over spray on glass.

Your car's windshield is probably the most overlooked surface on your car. Normal driving will coat your windshield with a variety of road oils, heated brake dust particles, pollution and over spray. Normal glass cleaners can not remove this type of contamination.

Try this test: Put your hand in a plastic sandwich bag and lightly run your fingertips over the windshield's surface. Chances are, it will have a rough, gritty feel. Glass cleaners will not remove this grit. It requires a high speed polisher (Makita 9227, DeWalt 849) or a dual action (Porter Cable 7424) polisher and a special glass polishing disc to polish the glass clean and smooth. Note: This kit will not fit the Dual Head Cyclo Polisher.
	Test glass for smoothness.
If you have a machine polisher, our Glass Polishing Kit contains everything you need to make your car's glass "like new" clear. The kit contains: 3 - Four inch, Velcro backed, glass polishing discs. 1 - 3.875 inch Velcro backing plate with a 5/8 thread for high speed polishers (Makita 9227, DeWalt 849). 1 - 5/8 to D.A. Adapter. (Allows backing plate to be used on dual action polishers (Porter Cable 7424). 1 - 11 oz. Autoglym Auto Glass Polish. 2 - Power Scrubber Microfiber cleaning cloths.
Application Instructions: Apply a Quarter size amount of polish on a dry polishing disc. If using the Porter Cable polisher, set the speed control to "4". If using a circular polisher, set the speed to 1000 rpm. Work on 1/2 of the windshield, polishing first in an up and down motion then in a left-to-right motion. Go over the glass several times in each direction. (Glass will polish virtually residue free.) Wipe off any remaining residues using the Microfiber cloth. Inspect glass for clarity and smoothness. Repeat if necessary.
	Apply Quarter size amount on dry disc.

Start polishing in an up and down direction.	Then go left-to-right until residue free.
After polishing, test the surface again by putting your hand in a plastic sandwich bag and lightly running your fingertips over the surface. It should be "smooth as glass!" Each disc will polish all of the glass on one vehicle. After use, rinse off the disc with water and allow to air dry. Discs can usually be used at least one more time before being discarded. Note: This system can not remove deep pits and scratches in glass. Do not use on Lexan, Plexiglas or clear plastics.
