I'm not talking about the reflector either... I'm saying the plastic on the inner face of the cheap aftermarket lenses, actually turns $#!T from age/UV/proximity to adhesives/poor seal, etc, and no amount of buffing will ever get it good again. Short of taking the light apart and buffing the inside of the lens, but that won't change the fact that the plastic ages right through any how.
This isn't confined to just aftermarket headlights, but it usually is the case. The most classic example of genuine factory headlights that go bad, are the Starlet GT headlights. But at least on them, the plastic goes milky in a consistent fashion. You can polish a genuine BJ lense back to good health, but these cheapies are doomed to stay crap. Gav. |

oh your talking inside the light...ive never seen a lens go ****ty on the inside of the plastic...it always the outside...happens to falcons ef/el, skylines, hondas, mazdas, lexus, toyotas...
nearly all headlights that were made between 1992-2004 in the plastic from the dealers origional moulds go ****ty after 3-5 years...

Yeah, I mean on the inside of the lens, or even through the thickness of the lens. That's why you can't polish it out. I know what you're talking about by polishing the surface micro-abrasions out which give it that foggy look, that's cool if the plastic hasn't gone off.
People hang $#!T on Neesahn, but my JDM headlights are still very clear after 12 years on the Pulsar. The vinyl on the other hand is another story... Gav. |

Most headlight lenses are polycarb and the problem is its tendency to yellow and cloud over time as a result of UV exposure.......polycarb without a UV inhibiting additive will show strong yellowing upon exposure to natural and artificial sources of UV (sunlight and HIDs)..... so apart from the nature of the plastic itself, lamp selection can affect the yellowing process!!

Did this with 2mins of hard rubbing, with toothpaste! Google it, it works (and has in this instance)'
From this: to this: crappy pics I know, but the tootpaste has got rid of around 75% of the dullness, will go over them again tomorrow...
