I wanted to put the build number that I received from RS somewhere on the car so I came up with the idea to make a laser etched professional label (we print these where I work). The only downside is that these labels are tamper proof so they cannot be removed without serious effort once they are applied. As a compromise, I decided to apply it the the fuse cover in the engine bay. That way if I decide I don't like it, I will just order another fuse cover. I also put my dealers name on it because they were very good to me. What do you guys think about it?
