It is possible you've scored a dud bottle - I have a handful. They just don't seem to have been mixed properly at the factory or the paint and carrier have separated to the point that even a young and an old priest couldnt magic them back together.
One good thing out of it is that the duds end up being magical glaze paints with paranormal properties. Flats become glosses and can feather all in one application, that kind of thing. I really lucked out and scored a Cavalry Red dud and use it a great deal for painting in replaced parts on Ma.K models. Just the right odd combination of translucence and weird glossy finish.
