I'm certain this would be a common issue, but I can't find the answers I'm looking for.

Basically I imported my GT-T at the start of the year, the headlights looked almost perfect when it arrived. Gradually over the course of the year the headlights have gone cloudy and oxidised. I used plastic polish on them and it worked to a degree, but as soon as any car wash solution hits them again they turn to shite. The driver's side particularly up close looks like the plastic is stressed, something a polish isn't going to remove.

My question is - how much would be reasonable to pay for second hand set? And is it common for the headlights on an R34 to do this? Or are the lens replaceable rather than buying the whole headlight? The headlights are HID, they weren't converted to halogens at compliance :rofl:

Permatex do a special Headlight Restorer kit...It involves sanding the face of the headlight smooth with very fine grit sandpaper then using a special plastic polish/protector to buff it up with. Best part is you dont even have to pull the lights out. Did it on my missus' car, her lights were real bad and they came up perfect. Still are and I did them about 6months ago..

Read my thread on polishing glass stains... you can use the same procedure on your headlights.

I recommend a heavy cut like Meguires Heavy Cut 9 on it... it'll come up a treat.

I honestly think one headlight's lens is beyond saving, the plastic looks stressed. I'll try and get some pictures tomorrow to show you what I mean.

So I guess the main point of my question is how much is a good pair of second hand headlights, or is the lens a replaceable item?

Edit: had a look at your thread. All most my windows and badly etched by acid rain. I'll get some of the Meguiars Diamond cut polish you recommended. Thanks for the tip :)

don't worry, your headlights aren't gone, they just need a MACHINE polish.

Final Inspection might even be able to quote you just a headlight polish, althought i'd recommend getting a full detail anyway, Stage 2 includes headlight polishing i believe.

Ah thanks for that, I'll have to ask them. But here's the photos I've been promising to get (I have higher res photos but I shrunk these down):

Passenger Side:

And from the front:

I think my use of PlastX has made them worse. As you can see, the passenger side head light is clearer but is pitted towards the top and has spots that are patchy on the face. The driver's side headlight is just terrible all over.

Do you think they're too far gone?

i don't know about the pitting, but i reckon the rest will come out fine. where bouts are ya? i might be able to pop round one day and run the RO over them (asked masking the surrounding areas of course)

EDIT: saw croydon, hmm... bit of a hike...

I've sent Final Inspection an email to see what they say. As you can see, it's not a case of them just being oxidised - something has happened to the plastic to cause that sort of pitting effect. What shits me is that it's happened over a period of 7 months or so. Prior to that they were fine :wub:

    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
