Getting micro scratches out of the rear window

I was wondering if anyone had a good product to share?

The scratches are very fine but trouble me that they're there. I was thinking of getting this product but it's for windshields (not sure if that matters that much)

Cerium oxide is the preferred glass polishing material. Be advised that even with a buffer and pads made for polishing glass it's a long slow process.

I've had great luck with this stuff.

Applied with a portercable and lake country red pad.

Removing scratches you can catch with your nail requires Ceriglass, a rotary polisher, and a messy long process.

It's funny you mentioned Ceriglass, I just ordered the kit, but my scratches are very minor (finger nail won't catch them)

Thanks the link to the other product, how long does that stuff last?

No polish will remove scratches deep enough to catch a finger nail. For that you need abrasive pads, and it's nigh impossible to get scratches that deep out without getting distortion in the glass. This is what you'd use:

I do it about once a year or so.

It gets off all the wiper smears, road film, bug stains, mineral etching, and other stuff that attacks your glass day-to-day.

They also have a glass sealant, but I haven't tried it yet.

Couple of tips with ceriglass:

1. Newspaper everything you don't want abrasive polish on, like paintwork.
2. Keep it wet with distilled water, you need it to be a slurry to work correctly.
3. You pretty much need to use a rotary polisher with glass specific pads

Thanks for the tips, the thing is the rear window where the scratches are is tempered glass, I'm concerned that a rotary would shatter it.

This is the kit I ordered:

I've polished my rear window with a rotary, no problem. Just be sure to keep the slurry wet to minimize heat build up. Have a spray bottle of water handy throughout.

In general with detailing, you want to start with the least aggressive method first.

If you're not confident in using a rotary, I wouldn't bother with the ceriglass stuff - elbow grease alone won't cut it.

Thanks for the tips guys, this dude here actually didn't use a rotary:



He uses the applicator that came with the kit.

Sure, but I'm not sure he's going for scratch removal like you are.

What he accomplished was getting rid of road film and rain-x judging by the water sheeting, which was probably causing wiper judder/squealing in his case.

You can accomplish the same with some Bon Ami 1886 powder cleaner as well, or that 1z Glaspolish I linked.

I'll try it with the applicator first then move the rotary if needed

I just tried with the applicator, it's better but micro scratches are still there, will have to use the rotary with the glass pad

What do you guys think of this product as a "sealant" for the rear window after I polish it?

Would the Ceriglass even need sealant after? Or is it just to make it hydrophobic?

I've seen reviews of Flyby Forte that are less than glowing. I also question who says it's 'the best in the world'. Google that and you can find at least ten pages of results. Glass doesn't need sealing, it does that all by itself. Aquapel works very well shedding water, so I use it on all my glass, including the outside mirrors.
