My 2009 87K mile Boxster 's headlamps are showing their age and slightly opaque surface, nowhere near MoT failure, but not good enough!

Asking here for advice on a good kit sold to use on these plastic lights.
TIA

Patience. Lots of 3000 grit and hot soapy water. More patience. Then a decent clear lacquer. Are they easily pop-outtable like a 986/987's headlamps?
Fair warning, though; once you've done it, you'll need to keep on top of it every few years.

Thanks for the speedy reply. A job that needs doing soon.

Maybe of interest:

After reading an AutoExpress review of lens cleaners I thought I would try the Armor All restoring wipes(!).

Arrived yesterday and followed the instructions and the improvement is really impressive, look like new from 3 feet away.

Just £12 off ebay, took 30 mins total time.
