What to do with dust in paint?

It depends on what type of finish it is.  If it is a flat finish. light sanding with very fine wet sand paper should do the trick.  If it is gloss paint, use a polishing cloth and water.  If you use sandpaper on gloss, it will dull the area where you are sanding.

would that do ??? the linked that i placed? i mean i have dremel polshing cloth wheels i can just wet it and use just my hands using it without attaching it to my dremel would that work??

Go to a hardware store or auto parts store and ask for embry cloth.  It can be used for many hobby related tasks not just for buffing out paint bubbles.  I have several sheets and keep a supply on hand for many projects.

I almost always have to sand out a few dust specks, so on gloss finishes I always plan on gloss coating the model. I use 1000 or 1200 grit to sand out these specks.  One can polish the area after sanding with that grit to eliminate the need to gloss coat.  So if the paint is supposed to represent a finish without a super gloss I sometimes polish instead of glosscoat. 

For the flat finishes I generally dullcoat, since the sanding never quite gets the proper sheen.
