i applaud your confidence to tackle a job like this...first you need to head over to your local barnes and noble, and purchase a "how to paint" book in their automotive section... read it, then come back here with any more questions...it's going to cover prepping surfaces for paint, the different types of paint, how to tape off the jams, gun control etc etc..

^that.

better to get a book thats gonna cover all the details, and then just come here to clear up any minor things. The people here who do have all the knowledge on the subject, dont have the time/incentive to sit down and give you all the info you'll really want to do a job like this.

I'm going to be painting my car as well, along with a bit of custom body work, and from the threads that have been started here that i've researched, i quickly realized this site wasn't gonna be the biggest resource in getting the job done. But there are several people here who will give you any tips/advice they have.
