That’s what happened with this Hummer H1 when it went to get a matte black wrap. Apparently the wrapping company painted over the Hummer’s original paint so the yellow wouldn’t show through any mistakes they made when wrapping the H1. This was found when the owner took the wrap off and was greeted with this site.
If you are getting paid to do a job, no matter the difficulty, try and do it correctly or you might find yourself all over the internet. The company who took part in this has yet to be released and lucky for them as it could ruin their reputation. Just imagine if this was an Aventador that you had wrapped and this is what you saw when you took off the wrap?
