E-Coat on new fenders

Did you sand them all off to confirm?
I have stripped two AMD panels and the metal is perfect. I’ve seen plenty stripped on the Internet. I have not heard one person say underneath the Ecoat was in bad condition. That why I question stripping it. If e coat is done right its supposedly the best protection. I would just like others to step in and say they stripped their panels and there was issues under the E coat. This is for AMD panels only.
