If u have a A&A auto parts store anywhere around u, i picked up this stuff called Night-Shades its in a spray can...turned out excellent

 

I went to a hobby store and got the spray tint you use for model cars. It was five bucks and I did my trucks tails black, but you can just put on a few coats to make them smoked, it works good just clean them really well first and it will stick.
