Hi guys,

I thought I'd post up some pics of a pair of headlights I repaired and restored. They arrived to me in average condition with damaged rear housings, some severe yellowing and previous internal lens coating work.

The damage on the rear housing was tidied up and the sharp broken edges were cut away. Some new plastic of a suitable shape was found and cut out to suit. Once I was happy with the shaping, I plastic welded the replacement plastic into place.

(The green is a ball of tape to stop any cut off plastic falling into the housing)

The outside of both lenses were wet sanded, starting off at 1500grit and working up to 2500grit (In the future I would go up to 3000grit).

This revealed the coating on the inside of the lens which meant the headlight had to come apart. It's hard to see, but there is an odd shape on the surface. That is where I've started wetsanding. Once done I then polished the inside of the lens.

The reflectors and internals were given a tidy up and the loose indicator lenses were fixed into place. Here they are back together ready for external polishing.

I used Scratch-X to begin with and worked my way up from using Menzerna 1000, 2500, 5000.

From this they were then hit with Menzerna UF, followed by 4 layers of AMMO Skin and AMMO Creme.

Thanks for the kind words guys. As has already been explained, the headlights can be removed with either a hot air gun or a putting them in the oven. I prefer to use a hot air gun.

excellent! i'd love to carry out these restorations, as buying good condition headlights are so expensive, and all it takes is a little time to fix up a damaged set. great work mate

Thanks mate. A little time and effort gives the best results ;)

we need ppl like you in sydney :(

Cheers. Shoot me a PM ;)

Great work on the 34 head lights btw

Thanks mate.

Hows the protectabt holdng up...i fond the heat from.the lights just tends to burn it off very quickly...

Really need to let some proper UV protectabt on there because once you strip off the coating it will cause them to yellow from.the inside out...

Have also heard about clearcoating them, haven't tried it tho...but a clear heatpeoof paint should work well in theory..

Rubbing the lenses back and clear coating them is the best option.

Digging up an old thread here, getting desperate.

Mine are pretty bad, followed a lot of advice via SAU and my mechanic who reccomended to buy a headlight restoration kit, but much of the discolouration is on the interior, not exterior.

I've just tee'd up a cut and polish for mine (black, looking very dull at the moment) and was wondering who might be able to do this work for me as I'm not that comfortable whacking parts of my car in the oven :P

I've never seen them fade on the inside. If they're that stuffed, find a replacement set.

Where are you located mate?

Latrobe Valley, Victoria - had a recent cut and polish done, cherry glaze etc (came up a million bucks) and spike of the lights, was quoted 100 per light. Sound about right? Not sure if that's interior or exterior.

I know some of these guys are just gonna be like "get new ones" but id rather have a crack at another solution before I dish out bulk coin because they are quite expensive

    • jeebus. glad you weren't under it while performing the stunt. Also thanks for the link to the wheel measurer, exactly what I needed
    • In the older stuff there were very significant differences 2wd to 4wd, for example Stagea had strut front end for 2wd and double wishbone for 4wd so it was not minor to swap. From poking around the 2wd v37, it *looks* like it might be more possible; some of the parts specifically have "2wd" stamped on them which suggests the platforms are more similar. You'd still want to start with a 4wd half cut to swap stuff from though. I'd suggest if you don't have a tune on the ECU you don't really need one on the trans either. Throttle mapping is in the ECU side (and you can always use a Roar Pedal if you want the throttle to actually respond to your foot), and really if you are happy with the stock power you probably accept the stock trans behaviour too....its all made to be "sporty" not racey.
    • So, updates. I have not washed the car since it came back from Tassie. I've driven it around a bit but not got around to actually sorting it out. I DID raise it because I cracked the rear bar leaving a hotel which was very distressing. Interestingly, the car drives more compliant now that it's raised a fair bit (5mm front, 15mm rear). Also noticed that my FR height was 10mm lower than FL. So that's now sorted out, too. I also bought this and had it printed: https://www.etsy.com/au/listing/1576422240/wheel-and-tire-fitment-tool-universal?ref=shop_home_feat_1&dd=1&logging_key=08f604d9fa4cc383550ba985e6ac85cd5cac7fbb%3A1576422240 Now, if I was smart I would have taken my brake calipers off to actually use this correctly but it was evident enough to me that in the region where the caliper was... there was nothing to hit suspension/guard/arm wise. So I'm going with "it'll be fine" after using the tool to hopefully very precisely measure the wheel clearance. Also while doing this, I had the very VERY bad idea of jacking one of the wheels/suspension arms up while the rest of the car was on jack stands. I did this to see how the arm would travel. This all was well and good until the car slid off the stands and went through a fence. So don't do that. Incredibly nobody was hurt and there was only minor damage to the rear bumper as the car didn't have far to slide, and had 3-4 wheels on it. The only damage turned out to be the fence itself which was easy to fix, and a little bit of damage to the fibreglass rear bumper trim. I had already planned to try a touch up paint kit to fix the time I drove into my garage door to see if it'd help in the interim before I get it fixed properly. I used the Dr Colorchip kit after looking online and seeing everyone talking about it. Yes it's made for chips and not huge broken missing pieces and I'll be 500% recommending it for stone chips after using it for stupid things like me. This took about ... 10 minutes and looking at the half assed photo the 30 second job I did on the bumper corner was almost perfect just by using the tiny little brush and painting it in. The sealact stuff to remove over-painting is really useful, so if/when I do it again I'll likely slather the touch up paint well over it and then clean it up with the cleaning solution. The wheels should arrive in a couple of weeks. I am still kinda confident after doing a stupid amount of measuring (and borrowing a set of 18x10.5+15) that they will not fit because I overlooked something, somehow and flew too close to the sun. ALSO R34 GTR guard liners do not fit on a GTT. I bought the undertray brake duct guides and had the wonderful problem of them not fitting my intake, my oil cooler and the liners themselves were even worse. Attempting to fit them won't work in general - You would have to cut them up as another poster mentioned as the bodywork is different on the GTT. At least I can try to resell them. So instead of cutting those up, I cut up my old already-cut-up GTT liners and extended them by using some PP plastic and drilling some 8mm holes for some nissan clips for the 'extra' bit. Because I was happy to cut them I was able to mount them pretty damn forward so I now have some semblance of guard liners, and the brake vents seal the bumper from the bottom. It sort-of-looks like this, to give some idea - If you look at the GTR and then the GTT this is when I realised that I needed to seriously measure as the inside of the rim area is entirely, entirely, entirely different and could not take any internet measurements for granted.   
    • If you are Ecutek tuned then these TCU tunes are anywhere from $550 to $700 usd. If you are not ECUTEK tuned, then it gets costly!    
    • Sorry to hear your HFM BM57 was faulty,  did you contact HFM I would hope they would be at least grateful for the information if there was some sort of manufacturing fault, you would hope they would be sympathetic even if your item was 2 years old if it had never been fitted. May I ask where it leaked from ?
