Well, I saw a dood on e30tech who tinted his. It turned out great. I've tinted many things with nite shades spray, so while it is apart to better mount the stainless rings, I'll pulled the inserts out and tinted them.
I guess the solvent in the nite shades is different than what the other guy used, because it actually ate the finish on the front and the lettering ran. Now it kind of looks like a motion blur effect in photoshop. Oops.
