Wet sand just like paint but spend a lot more time at the 2500 and 3000 level before buffing. It’s worked for me in the past but a lot of work.
Are you wanting to do it because of appearance or visual quality because you can make it look really good but its a lot harder to make it look normal looking through it especially if it’s on a part that’s curved.
Try it on a spot that isn’t so visible first.
Good luck.
