The "I have a lot of other projects" argument is a pretty lame one. If you have so many, why add another? You are making the biggest, in terms of hype and following, event of the year. People will nitpick you, and for the better. Until you know the track is basically perfect, you shouldn't paint it, and you should know that by now. It seems you use that as a reason to say "Well, it's painted, so I can't change it". Post pictures of it as just dirt, get it perfect, then paint it. Not the other way around.
