Thanks for all the info.
SmiterQ - thanks for telling me that, I was unaware. That explains why SwamprB paints only the damaged areas.

I will keep updating and posting photos as this project progresses. What started as a free grill has turned in to a fun project. I am excited to start taking it apart and cleaning it up. I am still a bit nervous about sanding down those spots and only painting the repaired areas and getting it to all blend properly. I hope I do it justice when I am done.
