If you degrease it good, then prime it, you can wet sand it to smooth out the finish.
By doing real thin coats, you won't really have a problem with lint because it will come off most of the time by rubbing it after it dries.
If your coat of paint is to thick, the lint will be embedded in the thick paint and be harder to get out.
I don't know much about Clear Coat though. Straight out of a can it's pretty thick and tends to orange peel from what I remember. An airbrush would be the best way to apply it I would think.
