Polishing scratches out of glass?

I recently picked up a 45 gallon via aqua tank off craigslist. It is in decent shape, but the glass has tons of very fine scratches all over. I've read up on polishing glass, and it looks pretty daunting, but doable. has anyone tried it?

I would fill the tank with water and see if you can see then. My 72 had some scratches in it when I got it, once it was filled they were gone.

Same with my 55g. With water in it I can't see any of them. Fill 'er up first and then make your decision.

I had scratches in my 110g and made numerous calls in regard to polishing them out. bottom line - no one thought it was possible without distorting the glass. My solution was to buy a new tank when it was time to move it.

I used my scratched up tank as a quarantine tank or for spawning fish. It's handy.

I didn't even think about filling it and then checking, thanks guys.

Mistergreen - i had thought of a quarantine, but since my biggest tank besides this one is a 20g, it seemed a little crazy. If it's horrible I'll just use it as a grow-out.

glass polisher is cerium oxide its applied mixed with water and a felt buffer
you can put a felt buffer on a angle grinder with right attachment
work ok on small scratches but anything deeper it will distort the glass by the time you get it out
