Single stage paint when mixed is mainly three parts. Base (color), Reducer, and Hardner. The hardner is geared at your question. This hardner acts as a clear and has a clear additive and (the clear part) is used at times to trim out interior doors, under hood panels, and door jams. So yes it has a clear mixed in, but it does not serve or do much protection for the pigment (base) (color). With all vehicles there is a paint code and when the mix is done, there is a line where it says to add 450B or something like that which is the hardner/clear additive. So yes, your type of paint if SS has some type of clear additive, but regardless will not serve much protection against fading.
