Hi Charles,

You will need to apply a UV sealant otherwise you will end up with headlamps the same colour of your car :P

I used the sealant from the Philips headlamp resto kit and 6 months down the track they are still good. The sealant they have is the same you will nee on new vehicles and leaves a rainbow colour reflection in some angles (dont worry, this is normal)

The plastic in headlamps does not actully contain UV filters so you will notice that enw cars will have the coating.

I was actully going to get some more sealant from the group that import the resto kit so I will let you know if i can get hold of some. Other option is to buy the kit which is ~40$ and you will get a bottle of sealant and applicator cloth.

Just a tip, do it on a sunny day off the grass and let it dry for four hours or so.

EDIT: Just talked to Invision Sales (distributer) and they dont ahve the bottles of sealant for sale seperately but they said there may be future developments changing this. They said they will contact me if something changes so I will let everyone know.

Hey guys,

I sanded back my headlights the other night and gave it a real good polish and I'm just wondering if UV sealant is required? If so, what options do I have?

Thanks!!

Thanks for the reply Matt :)

Yeah, I know those headlight restoration kits have the sealant but I don't wanna be spending $40-60 for a bottle of sealant, because I've already did the sanding and polishing already which would be included in the kits.

Please let me know soon if you could just get the sealant by itself, because my car is off the road for a few days and would like to seal the headlights before I start driving again :)

Hey guys

My headlights are murky as and was looking for a resto kit or guide on how to make them clear again, help?

Rob.

There's HEAPS and HEAPS of thread on restoring headlights.... Look in Cosmetic Section as well as DIY Section.

But a quick solution would be cut & polish, or even toothpaste.

If you want kits, try glassylite or some other one from Autobarn.

@Immacreflections - That's what I was looking at before, might give that a go :)

Yes, most of the time, just outside, unless you have leaks and water gets into the inside of the headlight, then you will need to take the whole lens off.

What changes them? The sun, the Australian sun changes the colour of the plastic, thats why I'm tryin to get some UV sealant, so it lasts a bit longer because I have to clean them again lol.

If you just cut and polish them, they will turn yellow again in a month or two, so with the headlights, it's kinda like a constant thing, just gotta keep cleaning.

Not much that you can do about it, because it's plastic.

REPLY TO YOUR EDIT:

You don't "need" to remove your headlights, you could mask around the light and cut & polish or just polish it with it on the car, but I took mine off coz I had to take my front bar off. So I thought I might as well take them off because it's easier for me to clean.

Hey Charles,

I doubt it will be in the next few days if they come out with something but will let you know if i ever do hear antything.

As for the C.Quartz, it will be great to give protection from scratches/blemishes but it will not protect from the headlights goign yellow. It is made to not break down due to UV light but it wont stop the UV passign through.

The coating that is supplied with the Philips headlamp resto kit is the same coating that the auto industry uses and it is there to stop UV radiation.

Im gonna ask around work tomorrow to see if one of our suppliers has access to the sealant. Hopefully one of them can help us out.

Although I will have to double check off the top of my head I disagree.

A reason you use waxes and sealants is due to them having protection from uv also, if you did a car half maintained wax half not by taping it down the middle. After 3-4 years if you pull that tape of you would see a clear difference and I'm 99.99999999% sure that is the case with c.quartz also.

Mitch

I had a different understanding but I will happily be proven wrong.

I will still maintain that the UV protectant that is used on head lamps will do a much better job than a wax or sealant at blocking UV as it is specifically designed to block UV radiation rather than a multitude of jobs.

Let me know what you do find out though Mitch as I am interested to know.

Well I stand corrected, the rep from CarPro who make Cquartz got back to me and they use a very high quality UV blocking agent.

The coating should last for a year if applied correctly.

@Charles: check waxit.com they have it for sale and are in Tulla.

He also informed me that due to the headlight plastic and what it is made from that some times guys sand to deep and can result in speeding up of discolouration.

Very true, the only layer of protection against deterioration is a surface coating.

Most older cars didn't even have a coating, hence why the head lamps on Skylines go yellow.

The coating applied in the auto industry is very different from Cquartz and is designed to last 10+ years. In the end, both will do the same job and I am sure one bottle of Cquartz will last 10+ years if you only use it on headlamps.

So in the end Charles89, go with the Cquartz, I will keep everyone posted if a UV sealant comes out from Invision distributes.

I actually sourced some UV sealant from a mate with the Invision kit, so I'll give that a go first on my headlights :D

Will post up some pics when its all done :)

      Duncan's V37.......race car?

      By Duncan · Posted

      But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.

      Duncan's V37.......race car?

      So, a bit of a side trip, but one that might be interesting for people with JDM cars and japanese head units. I know @Pac previously posted about a carplay/android auto adapter he installed which used the AUX input, and @V35_Paul put in one of the Tesla style units that replace both screens. The option I went with was a Lsait LLT-YF-VER5.87_2 (https://www.alibaba.com/product-detail/Lsailt-8GB-Android-Multimedia-Interface-for_1601187633672.html). Price was $1,150 for a single unit although they are much cheaper if you are willing to buy 2....$857ea. Make you you get the version 2 not version 1, it is faster and has a better UI - this is the manufacturer listing: http://www.lsailt.com/product/348.html. BTW if you've never bought from Alibaba before, don't be concerned....these guys can't stay in business unless they are responsive, ship fast etc, they were excellent (probably faster shipping than most local places) So, this was my task for a lazy Sat afternoon....looks complex but was all done in a few hours (it probably helps that I had some of it apart before so it was a bit familiar). I also decided to add a HD USB drive recorded at the same time and the unit also supports an aftermarket reverse cam (if you don't want to retain factory) and also AV in and HDMI out It looks much worse than it is, in fact in was genuinely all plug and play (no custom wiring at all). This video was pretty good (skipped a few steps), unfortunately they are an Aussie seller but no longer sell this unit (I guess Carplay/AA adapters are easier to install and much cheaper) https://www.youtube.com/watch?v=T5hJfYOB8Dg

      Nissan fuga 450gt android screen

      By Duncan · Posted

      That still isn't a lot to go on. I don't have a Y50 Fuga Head Unit wiring diagram. I can say that a lot of nissans of that age shared head unit plugs, so if you are in Australia something like this would probably help: https://aerpro.com/app091# You plug that into the car loom, then either plug the head unit ISO into that (if it has ISO), or you buy and ISO adapter harness that you wire in. Bit of stuffing around, but once you have ISO its easy to change things in future.

      just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.
