My Skyline's headlight had turned pretty yellow. I know aferx did a DIY on restoring headlamps, but mine was hazy and didn't have many obvious scratches. Also, I wanted to try this Meguiar's 1 step kit and see what results I get.

The Kit I used is the one:
Meguiar's Headlight Restoration Kit

It comes with a sanding kit which I did not use. (for now)

This is what the Headlamp looked like


First step is to clean the headlights thoroughly.
I covered the bumper only and opened the bonnet. So the only bodywork which was exposed was the fender and the Grille. I was really careful around them. But if you like, you could cover those too.

Then it is a simple case of attaching the supplied Buffing Applicator to your hand drill, apply the PlastX to your applicator and begin. I made a video of how I did it.

As in the video, buff the lamp until it is all gone. I got a decent result from just one go. If you are not happy with one, apply more PlastX and go once more.
Once the buffing procedure is done, just wipe the residue with a clean microfiber cloth.

Here is the before


And after


Very pleased with the results. Hope it helps others.
I found this kit cheapest on Amazon.
Kind regards,
Saabi

Wow.
Thanks for that. That had some great info. I will go down the sanding route next time.

It seems scary at first. Sandpaper? on your car?! but its really to remove the now broken down UV coating. Once you strip that off and polish it up, they come out brand new. Just make sure you get a wax with UV protection otherwise they'll turn yellow again fairly fast.

I usually do a quick 'top up' polish with the DA every couple of washes to stop them yellowing again.

Nice work so far :)

It seems scary and requires a lot of patience :D
UV protection coating is a must like you said. I think I will get it and apply it on top of this for the time being and see how it lasts :)

Thanks!

How long ago did you restore your lights properly?

It does take a while to do. Perhaps 30 mins per headlight with all the steps.

I did mine a year ago. Will be re-doing soon as I didn't have anything lower than 2000 grit sandpaper, need something more aggressive to start and take off that extra layer.

I do this daily on my own stock but with the R34 build I went a step further. Sanded them down with 1000, then back over with 1500. After that went two good coats of lacquer. Amazing finish. Obviously out of the car to do it! I have some slight staining inside the lens on one side so might take the headlights apart and see what can be done with that.




Rear lights and indicators all got the same treatment except with some black ran through the clear to tint them. Replaced all the bulbs with LEDs to compensate for the tints and make them more visble.

They definitely look sharper. 30 minute on each lamp is worth it I think. I will give this a go next time round.

Really nice work! They look brand new. Can't really tell the inner staining. I guess it gets more visible when you turn the lights on?

What type of Leds did you go in the back? Are they 1157s?
