I've recently refurbished the headlights on both my zt and ztt with a Meguiars 1 step kit that I bought from Halfords.
The kit comprises of:
1 bottle of liquid
2 sanding pads (4 grades)
1 woollen pad (to use with drill)
The kit:

I started sanding my lenses with a rougher grade, 1500 then 2000 and then moved on to the pads. After about 10-15 mins sanding with each grade, the lights had a wonderfully even mistiness that disappeared after using the woollen pad and cream.
My neighbours thought I had sneakily fitted new lights. They looked new!!
I'll bring the kit to Mays meet and we can give your lights a birthday if you fancy.
Also, I had bought a pair of facelift projector headlights a month or so ago, but one came broken. This leant itself for project work. I thought I could make some light protectors from the old lenses.
So, I heated the body of the light where the lens is black tack sealed and using a huge flat head screw driver began prising the lens away from the body.
It takes a huge amount of patience and time but eventually I could get enough purchase to pull the lens away from the body. I've not got much further than that so far.
