Very interesting Roger. Good info. Do you think if someone chipped or cut into the ridge he could tell if it's paint or sealer? It would not be green, correct? What do you think the number means? Did you see firewalls that bad leave the factory? I would say if the factory was concerned about a bad seal, they would be concerned about that not-so-nice-looking BIG mark? Once a worker tested and saw how big it was, why didn't they scrape it off right away, somewhat? Never seen that test before, Maybe others have trucks like that and will post. Good trivia.
