How to use cerium oxide correctly?

[gioprivatemvoe]

anyone can give pointers? what pad should be use? what speed (rotary)? and how long we must work on the product?
thank you.

[ScottB]

this sounds quite scientific ... maybe Mike Phillips can help. Isnt it a type of abrasive used in polishes ??

[gioprivatemvoe]

cerium oxide use in polishes?
hmm, never know it... :D
ok, we'll wait for Mr. Mike Phillips. hope he'll remember me from the other forum. :)

Are you polishing glass or metal with it?

[gioprivatemvoe]

Planning to use on glass, mate.
to remove minor scratch made by wiper blade.

Would you care to share a little more info? Where you got it, how severe of a scratch will it remove, does it need to be fallowed up with anything to regain clarity?

[gioprivatemvoe]

i bought it through my friend who own a body shop.
i think it can remove moderate scratch. but not to deep.
i dont think it need fallowed up product after using cerium oxide, cause the abrasive is like diminishing abrasive, it break down.
just simply top it with water repellent.

lets wait for Mike Phillips to explain further...
can't wait...

I have used this before and it is not a fun process. First the right combination of CO and water is necessary, to get the correct consistency of the paste you are ultimately applying to the glass. One of the hardest things about using this product, is you need the right type of pad to work this product on the glass and you cannot, under any circumstances over heat or buff/polish in the same spot for too long. It will leave distortion in the glass that is easily seen. If this is the windshield, you can wind up marring the glass to the point it is not repairable.

Ultimately with these precautionary information provided, the process is really not much different then polishing paint, in the sense that you want to slowly work across the affected area, not keeping the polisher in the same spot. You will need to have lots of patience, where unlike a soft or even hard clear coat, glass polishes down very slowly and you do not want to rush it. Ultimately, I have found that CO is much quicker at leveling scratches in glass, but can easily be applied incorrectly.

You will want to check your work regularly. If you want a less stressful way to level some scratches in your glass, might I recommend the Diamondite Glass Resurfacing kit. It is much easier to work with, less mess, includes all the pads and chemicals needed and with the proper patience can produce the same results. AG sells the kit in their store.

Should anybody care:

Applications

Cerium(IV) oxide is used in ceramics (http://en.wikipedia.org/####/Ceramic), to sensitize photosensitive glass (http://en.wikipedia.org/####/Photosensitive_glass), as a catalyst and as a catalyst support, to polish (http://en.wikipedia.org/####/Polishing) glass and stones, in lapidary (http://en.wikipedia.org/####/Lapidary) as an alternative to "jeweller's rouge (http://en.wikipedia.org/####/Jeweller%27s_rouge#Polishing)". It is also known as "optician's rouge".[2] (http://en.wikipedia.org/####/Cerium%28IV%29_oxide#cite_note-1)
It is also used in the walls of self-cleaning ovens (http://en.wikipedia.org/####/Self-cleaning_ovens) as a hydrocarbon catalyst during the high-temperature cleaning process.
While it is transparent for visible light, it absorbs ultraviolet (http://en.wikipedia.org/####/Ultraviolet) radiation strongly, so it is a prospective replacement of zinc oxide (http://en.wikipedia.org/####/Zinc_oxide) and titanium dioxide (http://en.wikipedia.org/####/Titanium_dioxide) in sunscreens (http://en.wikipedia.org/####/Sunscreen), as it has lower photocatalytic (http://en.wikipedia.org/####/Photocatalysis) activity. However, its thermal catalytic properties have to be decreased by coating the particles with amorphous silica (http://en.wikipedia.org/####/Amorphous_silica) or boron nitride (http://en.wikipedia.org/####/Boron_nitride).
The safety of the use of these nanoparticles, which can penetrate the body and reach internal organs, has been criticized.[3] (http://en.wikipedia.org/####/Cerium%28IV%29_oxide#cite_note-2)

why didnt you ask the friend how to use it?

[oldmodman]

I just removed a moderate wiper trace from a Toyota windshield using cerium oxide. I used a hard felt bob in a drill motor and it took a little over an hour to remove the 11 inch long trace. After you are satisfied with the level of removal it will probably be necessary to wash the car to remove all the splatter.

I actually haven't removed any scratches out of glass using Cerium Oxide, I've seen it done but haven't done it myself.

I have tons of experience polishing glass as in removing mineral water deposit spots, road grime and other gunk that build-up on glass as I did as lot of detailing in Oregon and because it rains there a lot the paint gets spotted and so doe the glass. You can't buff out a customer's car and restore a spot-free, high gloss paint job and leave the glass all spotty so I ended up learning how to polish glass and did this a lot.

As for removing scratches that's a much more involved process as you're removing glass particles where what I've always done is remove gunk off glass that was topical.

skizot's correct though, if you just buy industrial grade Cerium Oxide it comes as a powder and simply mixing it with water will work but it will have a tendency to easily splatter making a big mess. This isn't huge problem as you can wash the car to remove it since it's a simple water-base mixture.

The information that kb2ehj posted makes it sound like a real good idea to wear a dust mask at a minimum and safety glasses and gloves wouldn't hurt either.

Here's a pretty good thread on this topic by Dave Griffin aka Kickin Griffin who does writes very good articles on detailing topics.

Some good comments by Todd Helme on page 2 of the thread related to the inner plastic film and antique cars with original glass.

WOW! You guys went DEEP on this one. I knew I had heard of the chemical,but I could not remember where. Then it hit me in the Eye! When I was in college at Durham Tech,NC. We used the chemical in lab class. Opthalmic Labatory Mechanics. (making glasses) It was used to clean lenses,remove tents we had applied,and remove scratches. LONG time ago. I have the degree and detail cars. So I don't use it
in my business or in my water treatment job. Good info though!

WOW Durham Tech getting mentioned on the board....I work only a couple miles down the road from there. Taken a couple classes there also, kind of half hardily working on an RT degree.
