Good articles all. That's basically how I do my engine bay but I use Meguiar's Hyper Dressing after cleaning it with Meguiar's Safe De-Greaser.

As for metal polishing, here's what I did on the tail pipe of an S2000 at the Meguiar's clinic a bunch of us SoCal Crossfire owners attended recently. This was about 5 minutes work with Meguiar's Hot Rims Mag & Aluminum Polish. Not bad, huh?
