ok, first thing is get some 150 grit sand paper, well, get a lot of it! Start with taking anyting off of the car that isn't going to get painted (less tape time, this is a good thing) anything else that is, i.e. wing, fender flares, mirrors, take them off and sand them sepratly, these will be painted off of the car. If you are getting a professional paint job, take off your door panels and sand the jambs and behind the panels. You will want to scuff the clear coat so it is no longer shiny, but don't take it off. Anything you can take off of the car the better, badges, stickers, anything to save the painter time will make it cheaper for you. Remeber though, if you mess it up and he has to fix it you will get charged more. Your paint job is only going to be as good as your prep job, so take your time and make sure its right. best of luck bro.
