Crikey, don't hold back fellas

. I guess if you're going to post your efforts on a forum you'd better expect some stick.
Perhaps you should have only done one, guaged the reactions and kept the other one original. Personally, I think you should have split the case, removed the silver buttons and BMW badge (or at least masked them all off) and used a spray - the brushmarks are a bit too thick. Some sandpaper as suggested might smooth it out (again, don't forget to remove the buttons or mask off). Would be interested to see a V2.0 if you do. I'm not against the idea of a different coloured fob, just the execution in this case (sorry :? ).
If it comes to it, replacement key fob cases are very cheap so not hard to keep experimenting, or to go back to original
