Smoke Spray for Taillights

[ReD4000QuATTRo at aol.com]

Hey Listers!

I was wondering if anyone knew where to get the smoke spray for tail lights.  I work with Volkswagen aftermarket parts and they seem to have every shade of color for the VWs, but I seldom see a smoked tail light for Audis.  Therefore I have heard you can spray a smoke tint on your lights to achieve the darker shade.  Any ideas?
