How about instead of all the mindless posts like "OMG YOU DONT KNOW ANYTHING ABOUT PAINTING SO TAKE IT TO A SHOP LET THE PROS DO IT", a post with some insight? Perhaps some people like to take jobs on themselves and not always PAY someone else to do the work. And obviously nobody was born with knowledge so it was all learned somewhere along the line.
Before you take on a project like this, you should pick up a book about painting cars. It will tell you the necessary steps to prep and paint the surface. You can purchase primer, paint, and clear from
www.paintscratch.com and they can probably answer any questions you have about what kind of gun to use. You will want to invest in a decent gun to prevent clogging and so that you get an even spray. Painting definately takes some time to get right, so you should start off by painting small things first, and not your car. Good luck!
