It doesnt matter which way you start.
Wet sand in one direction. Then the opposite direction with the next finer grit. Very important to always keep it wet and rinse away grit periodically.

Great DIY...Much appreciated.

 

Hmmm.

Any update on how well the lights are holding up?

I don't have much oxidation yet, but there are lots of hairline scratches so I'm not sure if I should start grinding away with sandpaper?

Anyone try spraying clear after finished to avoid having to reapply sealant?

 

I think I'd avoid the clear and just deal w/ the sealant every so often since it comes in a pretty big bottle, should hold up real well from all I've read.
BTW, those cracks, here's a thread on those, might be worth a trip to your dealer

I was thinking of trying these

Gio, where did you pick up the foam polishing bit for the drill? I'm way impressed by your results.

 

Here is the LINK

 

wow, I guess I missed this post

anywho, here is a picture I took this morning with my cell phone.
The lights still look pretty good, not as sharp as they looked when I first did the restoration but considering I wash my G and rub on the lens every week I think they are still looking good

 

So I just completed this DIY the only issue is my passenger side is still some what foggy. The driver side came out perfect. Should I repeat the steps again tomorrow on the passenger side?

 

So I've followed these exact steps multiple times and my headlights are still coming out pretty hazy. I've done this several times and still not coming out crystal clear. I dont get it.

 

So, what if inside the headlight has oxidation?

 

I think removing the lens from the assembly is the only way to attack that issue.

I myself have not done it but I know there are threads out there explaining the process of separating the lens from the assembly.

 

Nice DIY
I did the same on my headlight, and also i installed a custom LED bulbs on my G37.
It looks better just like the new car. Very happy.

Why not find a LED bulb to make it perfect.
