Thats cool... Maybe a supervisor saw an issue the inspector did not and nullified his stamp so it want for a repair? I never saw something like that... quite cool

This is a first to me....

You hit the nail on the head Tom. "OK" stickers are easy to remove. In the case of the stamping(s) on the firewall, it's to hard to try to clean off the stamp impression(s). Often production inspectors, having been one at one time, will do what is easiest to let others know that the "PASS" stamp has been nullified. Leading them to check the inspection ticket for errors/problems found, that need to be addressed. At least that was the case in the plants I worked in.

So I'm wondering if they didn't include the spoiler and came back and taped over the holes (after removing the Camaro emblem) and then installed the spoiler.
What do you guys think?
