Such a pleasure restoring something to it's former glory like this.   

Really hard to believe these are 4 photos are of the same headlight.  The only significant difference between them is the "after" shots were late in the day so I had to use the flash.

The "subject" is almost ready for its coming out photo shoot now.

Looks great, what products? Its hard to imagine someone letting their headlights get so bad!

How'd the front go with the trip? Did you get many stone chips?

I could tell you, but then I'd have to kill you.   

It's typically a combo of wet and dry sandpaper (if really bad), and then a top-shelf plastic polish (to polish and reseal).

It was only the left one, so I'm guessing it was just some freak thing.  Maybe something splashed on it, or poor quality headlight from factory (unlikely).

No stone issues.  Just the bugs.

Oh lordy, the bugs...  those freakin bugs...

you generally see a lot of supras and skylines with fogged/dirty lenses... not sure what causes it, but it looks terrible

I get same results with Autosol. Way easier than sandpaper.

Allot of those Yellow headlights that you see on some supra's etc is UV related.

headlights usually have a UV resistant coating on them, those which dont have it, have a poor coating, or the owner has removed the coating by polishing the headlight too vigorously will do this.

I had a headlight scratched on a car once, and took it in to a polishing place, you could see the actual line where the UV protective layer was & wasnt. and after a year or so the non protected part of the headlght went foggy & yellow.

Definitely easier, but not ideal.  Sometimes it's too abrasive, and other times not enough.

Plus there's the problem of further oxidation and UV damage if you don't reseal.  Not a huge problem if you don't mind being back to cleaning them again even sooner than necessary.
