I utilized the tint paint that I got from a Japanese company on Ebay. It worked great and allowed me to control exactly how much tint I wanted. I removed the four tail light pieces and painted them all at the same time to maintain consistency of tint. It came out very well and I like it on my grey E53. I realize this is of no value without photo but the weather is crap here right now and I have no archived photos with the tint. Sorry. I highly recommend the tint paint if you know what you are doing.
