I will not mention company names but, I will say that on more than one occasion, when I used to do auto body collision repair work, we'd have to cut panels off of rust proofed cars. Once the panel was removed, we'd find a black spot about the size of the plug on the inner structure and that was it; no other coating anywhere else in the inner structure. I just used to laugh.

This thread reminded me of those days.

Not putting any companies down; just like with any company, some employees are better than others and the mothership can't control everything.
