Primer

I've been reworking an old project that i had done, a dashboard front Bezel on a Scion TC, so i stripped all of the paint, refinished the molding with filler and spot glazing, and every time i prime it i seem to run into some orange peel ont eh dried paint. what i'd like to know is what you guys use for a cleaner after wetsanding the primer. when i use to do body work on cars, i never remember there being this much of an issue shooting the primer over the filler, but it seems like every time i get a good wetsanded prime and i shoot it again to get rid of and parts that get stripped by the wetsanding here and there, it orange peels in areas. i dont typically use any solvents to clean it off, but i usually run the faucet over it to get rid of any dried wetsanding residue and dry it off with a lint free towel. any reccomendations?
