Yep, covering high beam adjusting bolts resolved fogging completely
Horizontal one was especially rusty, so it was probably single-handedly responsible for all the crap
High-beam horizontal adjustment duct tape cover
Low-beam vertical alignment
Zero fogging in both lamps after pressure wash in close to 0C temp
I've also had the same experience with a milky look that can't be sanded out from the out side. Plan is to get new headlights BUT
Does milky fog reduce the light intensity significantly?
i can only see the film 2-3 ft and closer, I don't see any difference but no measurements to verify. My 2003 GS430 is not pristine even from 20' (panel damage etc) so I am happy with being able to see at night as is.

That's a good question, and it definitely depends on how hard they have degraded in your particular case.
For me, i would assume it was not that bad, and they were rather defusing light, then absorbing it. At least from how it looked
With mines, at some point I felt a little too dedicated to the restoration process and also dropped in a pair of brand new Osram Cool Blue Intense
I am pretty sure HID bulbs do also degrade pretty hard with time (there is a youtube video, where 10 y/o bulb dropped 50% of its performance relative to a new one)
So that gave me a little better look, by color matching 5k LED Parking lights to new 5k Cool Blue Low beam, and performance is muuuch better.
Effectively, low-beam-vise, now it is a brand new headlamp, so I can't really tell what contributed more, the bulb or lenses, but if looks are not that important- I would give new bulbs a shot for sure
Also I am pretty sure there are plug-n-play led kits available, with only downside being too big, so big plastic cover might have to go, but that's still an option
Ceramic coating has not convinced me
There's pretty popular thread on reddit, that tend to generate more questions, then actual answers, and when I asked Gyeon directly, about UV protection effectiveness... I was provided with a link to the very same thread
Pretty disappointing to see company that actually manufactures stuff not having a clue about how it works, and if it does at all
PPF is complicated and illegal. so
Headlamps were left unprotected
And they do perfectly fine so far. We are having quiet a sunny summer here, and they are exposed to it well every single day
Yet, no signs of yellowing or haziness. So I am pretty sure at least some coating is there, and more time will tell how good is it
Have you thought about having a UV resistant clear coat spray painted on?
Sure, absolutely
It was mentioned before, up here in the thread somewhere
It's is a bit of a too intrusive type of protection, and quiet easy to mess up, if sanding is not right, dust and so on
So I really don't wanna go this way till I have to.
I do have experience, and I will do exactly that once lenses start showing signs of any fatigue, but for now, I am loosing nothing by keeping them as is
A sudden update
The lenses come with clear coat pre-applied.
Sanding through it at the shop showed the clear sign of a hard clear coat applied from the factory, so that's a big win
I guess those can be safely polished quiet a few times without the risk of compromising the UV stability
I guess whoever makes these owes me a free replacement for doing a whole marketing for them lol
