Today I started polishing the firewall. This is the first time I've ever done any polishing so it's going to be an educational experience.

After working for about an hour on one corner of the firewall, this is what it looked like. It's definitely a huge improvement, but not quite good enough.

Here's a closeup that shows I've still got polishing scratches in the surface. I'll go do some reading on the net to see if I can find any tips or tricks.
