Gordon Glass Co. Cerium Oxide High Grade Polishing Powder - 8 Oz

I purchased a well-used '99 Chevy C2500 pickup for the right price, and it included the (then) 23-year-old original windshield. And just like always, the fine semi-circle scratches from years of windshield wiper use made it difficult to safely see out during early morning and later evening driving into the sun. In the first photo I was able to capture the condition of the original windshield before I started. In the second photo I tried to capture the improvement, but if anything it looks even better than the photo shows. (Especially if the driver wears polarized sunglasses, which help to eliminate the reflection of the dashboard.) The results exceeded my expectations! In the third photo you can see that the windshield does look polished -- it simply looks new. As a matter of fact, without the fine scratches the Rain-x works better than ever. Best visibility I've enjoyed in any 20+ year old chore truck to date! In the last photo I am showing the very first vehicle I polished a windshield - it's my '02 CR-V daily driver that had the same fine windshield wiper scratches. (There was a bad spot where the travel of the left & right wipers overlapped just to the right of the driver.) Important Note: Although I was able to polish out the scratches using a small, hard wool pad chucked to the drill, it was much more work than it needed to be. On the truck I switched to a variable speed polisher (Makita 9227C or equivalent) and this is *much* easier. (Plan a full afternoon for an older windshield; polishing glass is a much slower proposition than it is for a similar square footage of automotive paint. (!) Disclaimers: 1) The rule of thumb about not being able to fully remove scratches deep enough to catch your fingernail is true. Even so, by rounding off the sharp edges, this polish will take the 'glint' away when the sun hits the scratch, and in many cases this can move a scratch from 'unacceptable' to 'good enough'. (The previous owner had allowed something to hang down from the roof rack and deeply scratch the rear glass, and was distracting in the rear view mirror. By working the rear glass I was able to make this defect much less noticeable...to the point where I'm more than OK with the results. 2) When reading through the reviews someone pointed out (correctly) that deep pitting won't be removed. By the same token, a whole lot of minor pitting *was* removed. If you look closely at the second photo you will see some of the deeper pitting remaining. IF this polishing compound was just as expensive as a brand new windshield, then I would have been disappointed by this. Instead, this polish is an absolute bargain, especially when it allows you to improve the driver's Situational Awareness for literally pennies on the dollar when compared to having the windshield replaced. And it makes your older vehicle look much newer/cared for. A win/win in my book. I've been wet-sanding/polishing paint for almost 50 years, and this cerium oxide is the first stuff I've found that actually works. For me, the results are well worth the time, effort, and price of admission. Hope this helps others out there who are driving older vehicles and need to improve the view --

Do nice job!

Pitless Windshield This stuff id great. I used a terry cloth on my Orbital Buffer put some water on it, then sprinkled on the Powder. I took my time going up and down and the back and forth. I would stop for a few min. let it dry and then go over it again with out adding any powder. Spent 30 min on each side and got most of the little pits that show up when a Car is coming at you at night that causes glare. The Car has 170,000 miles on it and the Windshield looks great! It is great stuff and I also used it to get scratches off of my GPS screen. Mixing cerium oxide in baby oil, I used it to micro-polish lathe friction-bearing surfaces (ways, cross-slide, compound tool rest etc.). This followed doing the same thing with silicon-carbide grit in baby oil. One can feel the surface machined roughness disappearing by the stroke. It only takes a few minutes of rubbing the parts back & forth. `works fantastically. The saddle/carriage slid so smoothly, I could push it with the palm of my hand and just watch the carriage wheel spin. REALLY nice ... Afterwards, adjusting the gibs is easier i.e. more consistent friction, too. Especially until mixed with baby oil, be careful to wear a face mask because, if either silicon-carbide or cerium oxide dust gets airborne and into your lungs, it will NEVER degrade or leave ... and would provide the agitation for accelerated cell growth i.e. cancer. Please take this SERIOUSLY and be careful using these wonderful, but powerful compounds. Cerium Oxide is the best polishing powder to remove glass scrach because the chemical and physical reaction. China produced 80% of Cerium Oxide in the earth. . High Grade Cerium Oxide polishing powder for removing fine scratches and scuff marks from glass and mirrors.

This high-grade polishing powder is a solid choice for addressing minor surface imperfections. It works well for buffing out small, fine scratches and restoring a clear, polished finish to glass surfaces. When used correctly, it provides a smooth and professional result for light maintenance. However, it is important to manage expectations regarding deeper damage. While it excels at surface-level restoration, it will not hide or remove deeper scratches that you can feel with a fingernail. For those more significant marks, this powder may not be enough to achieve a completely flawless look. Bottom Line: A reliable and effective product for light polishing and removing faint surface marks. It is a practical tool for glass care, provided the scratches are superficial and not deep-set.
