This afternoon I disassembled the grille and cleaned it up. Then, heeding advice received via PM from @AndyG, I chucked a #6 Course Rubber Duck into my drill and went to work on the surface rust.

I was also able to get out the slight dent on the lower left side. The reflection on the pic makes it look a bit wrinkled, but in person it's pretty flat, and now unnoticeable.
The back turned out well also, and I was able to get the surface rust off of the inside. With some paint I think I'll be happy with it.

Next, I'll poke some holes for the LED turn signals and it should be ready for paint in the back, and paint correction in the front.
Told ya so
