Theirs a couple threads on here about painting guns. What type of paint did you use? The Krylon paint is the best. You shouldnt have painted it and then put the wet side down on the newspaper. You should always let one side dry fully before moving onto the next section. As for how it is now, your best bet would probably be some fine grit sandpaper and sand it down and try again. Their are people here who are extremley good at painting and they can probably give you better advice.
