wanting to go for a 97 blackout int and ext, have a spare dash here and wondering the difference between sanding/painting and krylon'ng the spare has some wear marks where the previous owners keys rubbed and rubbed untill it was to black plastic... wondering if that would give me a smooth part if i were to just krylon it or if it would settle in the Bumpy texture of the dash.. also.. if i were to sand it is there any real way to paint the Airbag rubber so that it doesnt have the stock texture on it??

Sorry if this has already been covered (searched but didn't find what i was looking for) or if im posting in the wrong section.
First time ever attempting anything like this so any/all help is Greatly appreciated
