I recently acquired a steel 72 from 1969 that was vinyl coated. It had some areas that were broken through and had some rust so I stripped off all the vinyl coating and painted it. I had to use a pick to get all the vinyl out of the stampings, but they were all there. I used a stripper wheel on a small angle grinder which didn’t remove any significant steel. There was a some rust pitting in areas under the vinyl that showed no outward signs of rust, so I’m glad I stripped it. I ended up lightly sand blasting the rusted areas and then overall to give the primer something to bite onto.
I painted it with Awl Grip which is a marine system, I had the stuff around so decided to use it up. I used their epoxy primer followed by their Linear polyurethane topcoat.
After it was painted it went to hydro and it passed no problem.
Mine was bare steel underneath.
Just a hunch, but I somehow doubt that they would have vinyl coated a galvanized tank from the factory. That would be redundant and no reason to do that.
