Update: I finished the rest of the front grill trim and moved to the side trim. My experience has changed. The front looks great! I think The Never Dull is nearly as effective as the Blue Magic, and it is less messy to use if you are rubbing by hand. The side trim is not responding as well. The tarnish on the side trim seems different, tougher, making me think I may decide to replace a few of the side trim pieces as I don't think these 2 products will get the side pieces near the shine they returned to front trim piece. On the side trim I even tried letting the Blue Magic sit on the trim for a few minutes to get into the tarnish, before rubbing with more Blue Magic.

Side prepped and buffed with Blue Magic.
Top inside was tarnished too.

Top grill results with Blue Magic.
Front grill trim results, top showing results after Blue Magic. The lower part of the photo shows part of the trim still tarnished where I couldn't reach with the buffing wheel. A good before and after compare.
