I used this product in silver last weekend on my E46.
Goes on easily and the finish is very good. They give you plenty of paint too. I had more than 2/3 of the can left after I put on 2 coats. I didn't use it on my rotor hubs because I thought it was a bit too glossy. I used an aluminum colored spray engine enamel instead. As with all painting jobs most of the work is in the cleaning/prep.
