 And I'm going to guess it was probably a solvent-based enamel. I don't know that, but that's how you test it. Again, rubbing alcohol in a cotton cloth and rub with that, and it will definitely show up what the deal is. I mean, if it's shiny, it's an oil-based paint. And then you're going to need a transitional primer or a primered paint, a self-priming paint, one or the other.
