Best way to paint a FAST LSXR intake lid

[ArnieVXR]

I have a brand new FAST LSXR intake in grey which looks grubby already. The lettering is fading already. I had the same problems with my last one.

So, what's the best way to paint one of these? I keen to understand the best way to get it clean first, as I'm guesing the paint won't stick too well.

Thanks

Who could cover it with carbon?
