Carpro Ceriglass Window Polish

[COS80]

Really impressed by this stuff! I tested it on my old F-150 today, because I didn't want to wreck my Lexus' windows if this was junk... well, it isn't! These windows are much worse than the Lexus', too, so a better test.

The Ceriglass kit contains glass polish, a small polishing pad, and a towel ($18). I'm well-seasoned with polishers, so I also bought their glass polishing orbital pad ($6). It all worked beautifully! The pad is thin, so it's hard to control, but it makes the job a lot faster. The small manual pad is also necessary for the edges. It couldn't get the deeper scratches out, but it's likely that nothing will. Look at this difference!

Before - this is freshly washed!

After

Test: passed. I'll be doing the windows in the Lexus real soon.

I finally did the windows in my Lexus. Quite happy with these results, too.

The only caveat with using cerium oxide is that it heats up the glass surface really fast, so it's best to use a slow rpm tool on it. And do it in the shade. And keep it wet.

The worst case result is that you distort the glass surface, changing the optical characteristics; not a big deal on a side window, but might be on a windshield.

I've seen some people going to the extreme of having someone on the inside of the glass surface with a non-contact temperature scanner, just to make sure it doesn't get too hot. Sounds like overkill, until you think about the fact that once it's done, it can't be undone.

Otherwise, it's the bomb.

I used my Griot's BOSS orbital on both trucks. Toyota glass might be tempered harder, or perhaps the etching was worse than the scratches on the Ford glass, but I had it cranked to 4/5 on the 4th pass, and still didn't get them perfect.

I think the bigger warning, just like on paint, is the keep it moving at all times. Bad things happen if you hold it still.
