Preventing yellowing of lenses?

[The Chee]

Is that possible? Do you put wax or sealant on your headlights for that purpose? or it's better to just leave it clean.

Thanks

Use products such as Megs PlastX or Plexus to polish and seal your lenses.

I use Meg's PlastX on the head and tail lights, fog lights, clear plastic on the dash board, etc.

I wax my headlights everytime I wax the car. 2 1/2 years and 58,000 miles later the only headlight lens probs I have are rock chips/nicks
