Do you HAVE to paint over anti-stonechip ?

[T2-Nate]

I've sprayed a good coat of anti-stonechip over the cargo area and all of the parts that are covered with upholstery and panels after flatting and cleaning and priming, and will put some tectyl wax in all cavities and behind the panels, my only question is if it should always be painted over or does it do ok by itself?
Just thought it was cheaper and good fo sound deadening... looks ok
