Just keep rubbing, then polish off and repeat. You will see as you polish all the scratches go away.
In regards to the perch, I caught one and another FMer named Vook caught the other. They came from Lake Gogebic in the UP of Michigan.
If your looking for a real treat, go there for a weekend and enjoy some huge perch. Its amazing.
You may believe the grass is greener on the other side. If you take the time to water yours, it would be just as green.
