| its my understanding that a primer is thicker than normal paint (not by much though) and dosnt have a smooth surface. it gives the paint a smooth over all finish and a good serface for the paint to key too.
its also good to show up any errors (seam lines/ridges...etc) so you i always spot prime areas where i think there might be a problem, sort out the problem then prime the whole thing.
I use tamiya light grey primer, its a synthetic laqure so it fully cures enough to spray a hot paint like alclad over after an hour or two, ok to spray enamels and acrylics over it after about 30mins!
someone like bunkerbarge, alan, geedub or one of the more experienced guys might be able to tell you the real reasons why/how and what to do. i just do it because i know its best to do it lol.
