My headlight lenses have some fine swirls in some portion and I tried Meguiar's Plastix to polish them. I could hardly see any result. Anyone can recommend a better product? I thought those swirls can be buffed out but they're still visible in angle view.

I also heard that you can use some fine water sand paper to sand the swirls out. Anyone knows how to do it? I'm afraid that I'm gonna mess up my headlight lenses in that route.
