too expensive at the auto parts store, like 10 bucks for a can and it comes out too thick for my taste.
What I did to my last BMW was went to the hobby store and bought a can of testors spary paint called "window tint", they sell it so you can tint the windows on models and plastic rc bodies. Like $2.50 for the can. Wet sand it with some 1000 grit and dry really well (lint free, like a bath towel), then spray on two LIGHT COATS. If you really spray it on there it will get too dark, so be very careful.
Mine held up great in the sun, I sold the car but still see it around and it still looks good. Prep is the key, make sure you scuff em up good!
