So, many times it's been discussed what options there are for STi pink paint. While I think the closest match is still the custom paint sold by Grimmspeed (at a premium), I found two close matches that have been discussed by others on the forum. So I went and bought them for a direct comparison.

Side-by-side on a white piece of cardboard. Now you can officially see how close they are!

Just as a comparison, the Rustoleum has a little more "white" in it compared to the other two. Not sure how well that really shows through between my camera and people's computer screens.
