I did it! I got almost all the mess I made out of the wifeypoo's Volvo windshield.
A while back, I brilliantly scoured her windshield clean with a scritchy pad. Made a glorious mess of course. TBI's, they make you do brilliant things.
Read up on how to do it, and gave it a try. Took quite a bit of time, made one heck of a mess, but I got it looking pretty durn good. Especially in front of the driver, where I had spent extra time scouring the glass to get it extra clean (sigh).
Round one didn't go well. I used the Ceriglass polish and my blue buffer pad on my big rotary DeWalt buffer. Spent a good hour or two, and got nowhere. People said it worked well, but I sure didn't see it.
Round two did go well. I did further research, and ended up getting a one pound tub of cerium oxide (~$20), and used a 6" felt glass polishing pad (~$10). Increased the buffer speed, used a lot more cerium oxide than I had at first, kept it in a wet slurry, pressed pretty hard, and spent most of the afternoon out there on the glass. Seriously, I probably spent a good three hours at this. But, the results were great!
I've no idea if I removed glass down to the bottom of the scratches, or if I gradually moved glass molecules around. Either way, the scratches are all but completely gone. The glass is not wavy and there are no distortions when viewing through it.
The clean up afterwards is tedious. cerium oxide is the same color as brick dust, and just as sticky. With the buffer, I could fling it about 20 feet. So it covered the car completely. Probably took me a good hour or two of washing and re-washing the car before it got close enough to acceptable for her to accept it. I expect I'll find pinkish speckles for the rest of the cars life.
