I own a Collision/Resto shop and I see one thing in your pics that would raise questions. Looks like they put Bondo or putty over paint or primer. I would have stripped it completely like the other side. Hope it was etching primer. My Shop would not take in a job in if we were not going to work on it on a daily basis, The space in my shop is prize to let a project just sit there.
