Thanks for the feedback guys. I will try some polishing compound first to see how it does. If I'm not happy, then I'll try wet-sanding the area.
Since I am running the CHP equipment off the fuse block I installed, I think I'll take a suggestion and go under the hood to put a switch for the fuse block. That should fix me up I think.
Thanks again!
P.S. - And yes Andy, it smelled pretty bad when the cover was cooking
