glass scratch removal methods?

[|Tom the Bomb|]

So I have a bunch of very light surface scratches on a glass tank. I've been looking around and it seems that a cerium oxide and water mixture is the best option for removing the scratches. However I tried it and since the scratches are on a vertical surface, it did not work too well, the cerium oxide mixture was very liquidy and it just slide down, basically useless.

I have actually had luck with toothpaste in the past however this is also on the inside, so I'm not sure if toothpaste is safe for fish. Like the residual stuff. The tank is (obviously) empty so I will have the chance to rinse it off as best as I can. But still.

Are there any other "safe" compounds that I should try? for removing the scratches?
Suggestions appreciated, thanks!

Toothpaste and 800 grit sandpaper has been effective . On the oxide, make it into a paste

yes but my original concern was that it may leave residual stuff that may not be safe for fish. So I guess its perfectly safe then?

I generally take water down to area, buff, clean up with peroxide and restore water to the tank

Is there a trick for doing that, lol, mine always comes out very watery and it just slides right down

Following to see how you make out. I found a used RS170 for pretty cheap but it has a bunch of scratches

IME, if the scratch is bad enough to bother you…it’s permanent.

Well, ended up with just using a buffer + this

worked well, just made a mess.

After some more research, it seems that for deeper scratches you can use various (grit sized) sandpaper on the scratch, not sure about the specifics, never tried, but it seems like it would work, glass dust everywhere though, and then that creates a haze in which you remove with a polishing compound like the one linked above.
