Would T-cut or Meguiars work just as well?

It's not really coarse enough to cut through the crud. That's what the paper does effortlessly, and the G3 compound(or whatever expensive magic potion you might have) restores the finish.


This was really bad, so it was sanded with a couple of passes of 1000 then 1200grit paper which created the dull but even finish:






A quick buff with the compound(by hand) produced a usable lamp:

I'm going to use the paper you recommend for the grud, but T-Cut should restore the finish?

If you have T-cut, then try it. But it's too fine to be particularly effective. If you have to buy the wet&dry paper, then it's probably worth getting adding a sheet each of 1500 and 2000, which might bring the finish closer to a starting point for T-cut. Which will still be hard work.

I. Did the 1000 then 1200 then 1500, lots of water then finished them off with G3 and a polish with autoglym.

My formula as well BG  . . .  G3 with a polisher though . . much easier

I used the wet "n" dry paper method then lacquered them with an aerosol lacquer and they stayed bright and shiny for a good few years until I sold the car. Makes such a difference to the look of the front end!! Need to do them on this one now as they are going yellow as well. Won't take them out just do them in situ and stick a bit of paper around the lamps when lacquering.

If you use wet&dry for the hard work, then very little buffing is necessary. I can do both by hand in the time it takes to get the extension lead and polisher ready to use, let alone actually doing the job and cleaning up afterwards. Most of the lamps I've done have been off the car, so some method of holding them would be needed for machine polishing.

Helped out an elderly neighbour today and did their lights as I noticed the plastic was rough and on the turn 

G3 paste & 3000 Grid Wet and Dry with lots of water, then lots of water and 3000, then 5000 and finish with 7000 grit 

Polish with AutoGlym Super Resin and then a top UV protector 

He was over the moon with it.  Here is a before and after.

It wasn't an Omega  , but happy to help him out.

Mine was suffering the same, being a tight arse before buying a lens polishing kit I thought I would try some of the things I had hanging around in my shed. I found that Auotsol metal polish did the trick, needed a lot of elbow grease too but worked a treat. The guy I car share with even commented on how much brighter my headlights were the other morning so it must have worked.
