had a etch in them that would bight into the base metal . Epoxy actually cross links into the metal on a molecular scale. That is why grinding is necessary when welding oil pipe line. When epoxy coated oil pipe first came out there was problems with the weld. So they took a look at the pipe with an electron microscope and low and behold the paint was not just laying on the surface.
I was shown pictures of it when i took my welding course in the 70s. Of course they might be fake like those pictures of the men landing on the moon…..
