Are you refering to "Polyester primer"? Polyester primer is like a spray on "bondo". I like the stuff personally. Instead of applying a coat of plastic filler ("bondo") just spray a few coats of polyester primer, it is much easier to sand and finish off. Plus it can be painted over with no need for more primer or sealer.
