Sanding headlights

[BrianMcLeod]

When sanding headlight with the PC to restore them what speed do y'all use on

500 grit

800 grit

1200 - 1500 and final

3000 grit

500 grit is pretty aggressive. Most headlights won't need that. But for sanding you won't need a high speed. Maybe around 4 on the pc.

In this video (cheesy I know )

I started with 1,000 and finished with 2500

It was all done by hand though. I agree 500 is pretty aggressive, but at times it might be necessary.

You can do

500

800

Still wondering if one can go from 800 to 1500

And skip the 1000?

Anybody know?

I've actually went from 800 to 3000 with great results. I've attached some photos

How do you know you've taken down of the oxidation when sanding? I tried wetsanding for the first time on some practice lights, I started out with 500 ended with 2000 then compounded and polished. After polishing it still wasn't clear so I went down to 360(lowest grit I had) and it came out better but looks like I will have to go down even lower.

Did I do anything wrong or just didn't take out enough of the oxidation in the initial sanding? I used a rotary with 4" wool pad when compounding and polishing speed 3.

800 should be enough to take out any scratches and oxidation. Do cross hatch sanding so you know if you removed the previous sanding marks. Use a bucket of soapy water and rinse often..work clean.

I just use the eye test, usually if by the time I'm finish with 800 and its not clear I know I need to sand a little more.

Sorry for the thread hijack. I tried the same process on these headlights today, you can see the left side was pretty bad. They made a big improvement but if you look closely the drivers side is much clearer(had less oxidation originally). I didn't even have to wet-sand it just compound and polish.

Passenger side went down to 360 and in the sun you can still see a bit of yellowing and not clear like the drivers. What am I doing wrong? I'm going to go down to 220 and do cross-hatch unless im missing something.
