Reconditioning lenses question...
 
2 Attachment(s)
Has anyone who has reconditioned their headlamp lenses seen this streak (I marked the second picture so you can get a reference to the area I am speaking of)...

It looks like it may be in the inside of the lens? Anyway, no matter how much I wet sand it with 1000 grit, it does not change.

I am thinking that since it is an ultra clear spot I should just leave it be and move on to the 2500 sanding.

Any thoughts?

Well, whatever it was, it can't be seen anymore...

Right lens completed. Not a great job, but it will do for now. Compared to the untouched passenger side.

Good job, man! Both my headlights look like your passenger side. How long did it take you to clean up the driver side?

As far as the streak, I don't have it so I can't provide feedback.

Thanks,

I worked the 1000 grit for about 10 minutes total time.
I worked the 2500 grit for about 2 minutes total.

I think the result looks good in the picture, but the lens is still ten years old, so it will never look as good as new cars I see with new crystal clear (like fresh glass) lenses. But it's a lot better than it was.

I think I will may try jewelers rouge on the passenger side as a final step before retreating.

Nice!

If you do try the Jewelers rouge post the final results.

Here's a video DIY for the 3M kit. You can never really wet sand and buff long enough! Just get it to your liking...

Is there any coating to put on after the sanding and polishing are done that will help slow down deterioration again?

Yes. It comes with the kit.

Ah...suppose I bought a range of sandpapers from 1500-4000 and wet sanded the lenses. No kit. What should I use to protect them after polishing?

Sorry. I have no idea what the chemical makeup of the protector is. The kit costs about five dollars. I would just get that.
