Our weather is so moderate here, it's hardly worth it.
Perhaps if you lived near the ocean, or an area with a lot of winter weather where they're treating the roads constantly, it might be worth it if you don't take care of (ie. wash regularly and hand wax annually) your vehicle.
Actually, a clear coated vehicle shouldn't be waxed so soon anyway. The clear needs to harden to protect your paint, and that takes at least 90 days. First wax should be after enough time has passed for that process to occur.
Wait - is "Auto Armor" a chemical application or a clear plastic covering over the nose/mirrors/front of hood? If it's the clear plastic, then depending on the car and the price it might be worthwhile...
