HOW TO REMOVE SCRATCH ON GLASS TANK

[daniella3d]

+1 on that. Cerium oxide can only remove very small scratches and if you manage to remove the deeper one you're going to create a magnifying glass effect, very ugly.

It does take a lot of time and effort to remove even just a small scratch. I simply gave up the idea after a while. Most small scratches don't really show when the tank is full of water.

If you can feel the scratch with your nails, then it's gonna be there forever.
