Cerium Oxide use?

[Brently]

Okay so I recently came across a good deal on a 175 gallon bowfront tank with a sump. Only problem is the tank has a good deal of light scratches on the inside, my guess from cleaning with a float magnet. Anyways I have heard of using cerium oxide to buff out minor scratches. Does anyone have any experience with this? Do I need to use a drill or can I do it by hand. And does using just the cerium oxide and a buffing pad work or do I need to use other things as well? Thanks for any help.

best with a drill and a polishing wheel yes, by hand it going to be allot of work, apart from that and the cerium oxide, just water and cloths/paper towel

there are loads of tuts on youtube so you can see the process, its not to hard at all...but by hand it'll be a pain in the _ _ _ _
