Dino windshield Glass: removing windshield wiper scratches

For decades my front windshield has had three windshield wiper arm scratches right in front of the driver's view and I'd like to remove them.

They are fairly light but my fingernail does catch on the center of each. I tried polishing them with cerium oxide and although it reduced the tails and lighter marks, the deep scratches still remain although this is the best it has looked in years ... but not quite there yet

I had the glass out of the car so I am saving a lot of prep work that an installed window would require

I watched several videos on this product and the results seemed amazing - but too good to be true?
Scratched Glass Repair,Glass Polishing, Scratch Removal Damage Repair

so I bought their kit
DIY Glass Scratch Repair Kit - Glass Scratches Remover GP-WIZ System 3'' 75mm

First step was to clean the glass very well, I used spray away and 0000 steel wool and then selected starting point. I chose the mid grade green pad and after two green pads the scratch was gone from all 3 locations with a consistent grind area,
just like in the video.

Blue pad is the finest so follows the green pad clarifying the previous grind

The haze diminishes with the fine pad, there is no sign of the scratches.
The glass is gaining more clarity
The piece of tape is protection for the glass ID. The "bug" has been taped off to preserve the original identifying marks

After buffing with Cerium Oxide and wiping up the compound this looks really good.
Wonderful clarity, flowing your hand over it, I can't detect any surface edging or waves

Big win, I'm very happy

Unfortunately when you start to look, you can find more than you want. During the cleaning process with SprayAway and then 0000 steel wool I noticed this nasty scratch beyong the three wiper marks. This one is actually deeper than the 3 wiper marks and located nearly center of screen so very visible and most prominent.

No Bueno, this one has got to go!

After examining the depth, I still refuse to go with the most aggressive red pad and select the mid-coarse green pad again to start the grind. The grind goes easy and is set wide to smooth the whole area as indicated by the nice, even haze. Look closely and the original scratch is still there - we will need to continue grinding after this photo.

The MOST important part of the whole effort is to contain and control the glass temperature. In this shot, the scratch is not quite completely gone, but the area has been cleaned and is cooling down before working on again.

Dino reproduction glass has a bad reputation for not being anywhere close in thickness to OEM original so it is even more important not to cause anything bad to happen to this OEM glass. Because of this, I am taking it ultra slow and not building heat which is the safest way to proceed. Unfortunately this means the majority of the time I am touching it for temperature inside and out, waiting for cooling, and wiping it off.

As such these pictures may be misleading on how quickly things happen. slow as a [email protected]!

Proud of my even haze using the green pad, I move on to the blue pad for a much finer grind, almost polishing. I also push out beyond the edges of the green pad limits to feather the edges out. As such it takes a lot longer to get an even haze as well as waiting a long time between grinds to allow glass to cool.

Finish with cerium oxide polish, cooling along the way.
This blemish is gone, so clear that I need to point out where it was because you can not see it any more.
Another success!
