Once you've stripped them down once (I use the Blue Magic now to strip them), you can keep up with them pretty easily.
I buffed Turtle's out back in the day, and they looked like new lenses. Now they just need a little maintenance every time the car is waxed.
I need to buff out Ron Burgundy's like I did on Turtle, I'm jealous looking at my handiwork from back in the day.
I agree with worthrj, the Florida sun makes anything you do to the headlights a temporary measure at best.
