Wierd -- not waxing chrome.
If you don't wax chrome, it's a lot more susceptible to damage, pitting, peeling, etc.
I also wax everything that's not plastic except the headlight lens -- including the water hoses and carb rubbers when I've got the carbs out. Waxing the rubber bits helps prevent oxygen/ozone penetration keeps them from drying out and cracking.
I'm running an exposed filter box but I use ArmorAll (plastic cocaine) on that. It makes it shiny and it looks like it's supposed to be that way.
I should point out that waxing the tires and brake rotors is a really, really bad idea.
