removing fine scratches from glass tank

[zulu_principle]

Can you feel them with your nail ?

If you can there is almost no way, so the 40 odd glass guys I talked to said.

If Wendell says it can't be done I'd say it can't be done. I think instead of removing the scratch you'd have to fill it first with something then polish the filler. Trying to grind it out or polish it out would only compromise the glass and give you a weak spot.

You could try something like speedy auto glass, try to find out what they use to repair car windshields but it may not be reef safe or suitable for underwater use.

I've tried using two part epoxy on glass and found it didn't stick, water got behind it and it lifted off so don't waste your money on that.

Let me know if and where you find any - I would be interested in some. I looked at Canadian tire for any glass product that contained some of that compound, but I didnt find any. I think that I put a few scratches on my new-to-me tank while cleaning it out...

I think you can buff the scratches out, but the problem is that you create a "lens" from the depression in the glass where you've removed the material. That creates a visible "wow" in the glass that is more noticeable than the scratch, in most cases. If they're not deep enough to feel, then buffing them out won't usually remove enough material to create a distortion.
