I heard the headlight lens might need to be sealed (i.e. a special type of wax or something to polish the headlight with) as the lens will fade again.
The process of sanding down the lens removes the UV protection layer on the headlight lens and the fade and yellowish layer will return quickly
How long do peoples lenses last without after treatment?
What have people used? Or would a plastic polish be sufficient?
Need to do the headlights on my prelude as they are getting quite bad now
