For light yellowing, you can get away with a product that Just Jap sells. It is a japanese polish specifically for headlights, with japanese writing all over it. You can also use a generic headlight/plastic polish from companies like 'Mothers', it will do the job, but is slower and requires a lot more patience than the Just Jap tube. In the old days we used to use toothpaste and then car polish. The old 750cc Suzuki two strokes [waterbottles] had a plastic lens on the speedo and tacho, the toothpaste/polish thing worked fine [probably prevented decay and gave a fresh mint finish as well.......lol].

I bought a tube of that plastic cleaner Just Jap sells. Works great! Only used bout 1/4 of the tube and requires very little effort to remove the yellowing. I found paper towl from out the kitchen works best to apply it with.

i used meguires scatch-x on mine with a woolen buffing pad on the drill. took longer to find the extension lead than it did to polish the lights up. took about 10 seconds a light and very little energy.

Does anyone know if the R34 Plastic headlight covers can be ordered as separate parts direct from Nissan? (simply the cover itself)

Even at $200/300 a Pop Id be quite interested in replacing them wile the car undergoes a full paint job.

Well for starters I did mine the old fashion way called up my mechanic back in Singapore. And he taught my the old way before the polish for this and that came along.

1) Tube of toothpaste

2) Motorised Car polisher if you have 1 if not your arm will do.

3) Apply on headlights and alittle water (like brushing your teeth)

4) You will start seeing the toothpaste (foam) start turning yellow.

5) After you are satisfied wash of with water and have a look if its crystal clear and no more yellow to your standard (if not continue again)

Cheap and easy way. I did it it removes all scratches and yellow on the lens and have lasted my now for more than a year no problems.

Toothpaste have got sanding effect as they contain microscopic beads to help remove our plague from our teeth. So its sanding power is finer and purer and have no worries about if you sand too much of the coraser sand paper or not leaving us in a limbo when doing it. For toothpaste as its so so so so fine you have no worrys. Try it and you'll see the result and peace of mind when doing this.

Cheers

i think the idea of taking the time to rub it back with fine fine sand paper, or the toothpaste, or both is to remove the yellow, not just make it shiney till its gone. sanding them back as he has will make the yellow stay away alot longer than just polishing them up.

when i bought my car they just polished them up with the car, worked fine, but came back fast. since then ive sanded and polished mine too. months later still looks sweeeet.

Indeed. I guarantee it will last longer than just polishing them up with Plastx. It's been almost a full year with no signs of going yellow.

Here's another set I did for all the non-believers

Before:

I gave the headlights in my 33 the treatment a couple of weeks ago... and I must say... WOW!!! They really look like totally different lights! They were REALLY foggy, did the 800, 1000, 1200, 1500, 2000 grit sandpaper trick then polished with Meguires PlasticX I think it is... came up looking like brand new! Unfortunately I didn't take any 'before' shots to compare to...

Here's a shot from a while ago... not that obvious but see how the front of the lense is very visible...

And here's a couple after the sanding/polishing... notice how the front lense is now practically clear?

A LOT more noticable in real life... especially when you remember what it was like beforehand... I really wish I took before/after photos for comparison!

i think i f**ked my lights up!.

did all the steps right but when i used the megs plastx it totally fogged up my lights worse then ever!! and i did it over 2 times..

help anyone please!! and it seems to be permanent now, only did 1 side tho so thats even more f**ked lol..

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
