				| Started sanding the ribs
 I am using these sponge sanding products. They work great at rounding off the edges of the metal. I use the Scotchbrite wheel where possible. Then I use the 320 grit sandpaper sponge on the spots that can't be reached by the Scotchbrite wheel. I also bought a  sandpaper sponge that comes in a thin sheet. It allows me to get between the rib flanges on the corners. It's also great for sanding the rib holes.
