Maybe i didnt clay and skip to use AIO on it. I always wash my car myself. never bring to outside wash before.

Beside meg ult compound or polish. Any others thing can use? proper polishing as in using machine to do it?

Thanks for the advise.

straight go to AIO without checking the paint condition is dangerous IMO
if a lot of particle embedded, you will scratch the hell out of ur clearcoat when they are sheared off by the pad while you are polishing

meg ulti polish and compound is the go to for lot of us to correct paint. it is more effective doing so

you can polish by hand too, but it is will take a lot of effortsssssssss. you need consistent pressure and motion to remove paint. I could not do it

Soooo, I had been having an annoyance with my relative's Myvi headlights whenever I see the car. It is quite an old car, about 2006-2007 model. Today she managed to spare abit of time for me to polish it while she attended her class. Just sharing some pics of the work:

This is how it looked like at the start. Both sides are almost equally faded and whatever film protecting it long gone.

Started with 1000 grit wetsanding by hand using forward-backward motion. Alot of brown water dripped off cuz I didnt wash or clay before starting.

Followed up with 2000 grit wetsanding by hand using left-right motion.

Final wetsanding by hand with 3000 grit using forward-backward motion.

Just to show the left one after completing the same wetsanding process.

For compounding, I used Meguiars m105 with microfiber cutting pad. For polishing I used Meguiars m205 with black finishing pad.

Finished result under semi cloudy daylight. Didnt have any appropriate protection product to apply, so left it as it were.

For this short detailing work I used the following products:

1) Machine: Rupes LHR21MkII, 5" backing plate and washer mod, mostly running speed 3 throughout the process.
2) Sanding: 1000, 2000, 3000 grit sandpaper
3) Compounding: Meguiars Microfiber cutting pad and Meguiars m105 Compound
4) Polishing: Meguiars Black finishing pad and Meguiars m205 Polish
5) 3 regular microfiber towels

Overall had only about 3 hours to get this done cuz she needed the car back after that. All the work was done within 1.5 hours. I think the lights came out okay considering its age. When turn on the headlamp lights can still see the little hairline cracks inside but cant do anything about that.

Want to ask some advice.

What is the proper name/terminology for dark lines seen in the below pictures?
Washing doesn't remove it.
What should I use to remove it? Will a detailer do?

Thanks!
