Since it's fall again in New England and I’ve found myself unemployed I thought this would be a great time to start some prepping for winter. That said, the windshield on my 1999 Dodge Dakota is the original so that makes it almost 14 years old.
The glass is typical factory and after 13 hard New England winters it exhibits all the tell-tale chips, pits, spots, and minor scratches you'd expect.
Carpro CeriGlass comes in 2 sizes, 150ml or 500ml and is available in kit form. The 150ml bottle is a convenient size and squeezable making dispensing the product accurate and easy.
CeriGlass contains no strong dissolving agents, which can damage your skin. CeriGlass is a mild abrasive polish proven to work on glass without distortion. It can also be used to clean and brighten chrome and other metals and to polish hard plastics.

CarPro CeriGlass is specifically formulated for glass and contains Cerium Oxide, a special compound specifically for polishing glass. According to CarPro, CeriGlass will remove stains, hard water spotting, scales, road film, and stains.
A nice feature of CeriGlass is it can be used with a machine or by hand. By machine CeriGlass can be applied with either a rotary or dual action polisher so there’s a lot of flexibility built in to this product.
Because I like rotary machines I decided to my
Flex PE14-2-150. This rotary is a bit smaller and lighter than my Makita 9227 and I thought it would be better suited especially at an arm’s length.
Carpro CeriGlass is a white creamy product, similar to what you see when using a paint polish. Apply it directly to the pad, place it on the glass, then switch on the machine.
CarPro also recommends using this product with a glass buffing pad but the only pads I had on hand were the
3” glass pads by Griot’s…
I taped the plastic trim to protect it against accidental contact with the rotating pad. While this was a great idea I should have anticipated slinging and as you can see I wasn't disappointed. Next time I'll cover those area's I want to keep sling free.
I worked CeriGlass in a crisscross pattern and on speed setting 3.5. I felt this was an optimum speed as my arms speed was intentionally slow wanting to give both the product and pad time to work. When the product seems to be thickening a squirt if clean water is all that's needed to get things working again.
While CeriGlass is messy but it's also water based so it's very easy to clean up with regular soap and water. I mixed up a bucket of regular car wash and with a soft foam wash pad everything cleaned up easily and completely.
Once everything was washed and rinsed I dried the area using my electric leaf blower. Without rewashing it with a dedicated glass cleaner and waffle weave towel I could easily see how clear the glass had become.

Conclusion
CarPro CeriGlass is a great product for removing small defects, stains, water spots, and road film. It's easy to use by had or with either a rotary or dual action polisher. There are no special skills or precautions to be concerned with and my results were spectacular.
Pros: Easy to use, works very well, water soluble, removes stubborn spotting and stains.
Cons: Not for use on paint. Messy but as long as you plan for this it's really not an issue....
