Don't drive your car.

Seriously, that's the only way.

take it off, clean the living crap out of it, polish it up, but before waxing, clear bra it.

then wax that.. put it back on.. enjoy.

Or.. let it get all gnarly the ol school way. I vote for #2.
Be happy that scratches from use never actually went out of style.

 

Now you understand how it feels! I get that on my car a lot. Don't worry just keep it clean, make sure to clear bra it. You know how bad AZ rocks take a toll on our paint and bumpers.

 

LOL... my 1st Moulding is vacuum too, your going to have to clean often if it bothers you that much.

 

I've seen these.They are operational..have sizeable gaps due to this.
Anyway to rig screening at the front to guard against road stuff being
sucked in?Seems to be possible.It would not be noticeable as its under the car.
