Hi everyone, after using the yellow cap method to restore two of my cast iron pan (3x2 days in a plastic bags + scrubbing between each session), I wonder if one of my pan (the little orange) has a coating on the inside or if it is just an old seasoning? The yellow cap doesn't seem to damage or remove it at all.

Photos of the restoration below. I haven't seasoned them yet.

Thanks for your help.
