Ok, Im prepared to catch some sh!t because my screen name has "rat" in it and my car is 40 years newer than most of yours so If you have an issue, please read my intro and hopefully that will clear things up for you. Now that were past that; Im workin' on painting my 65 cadilllac. This is my first "Rod" and Ive never painted anything before. I think that Im finally finished with my sanding and my plan is to paint it rustoleum "Satin White" since a) the car was originally white and b) everybody else paints their sh!t flat black and its tired and completely uncreative. What I was wondering is since its rustoleum do I need to primer it first or just shoot the satin on the car after Ive sanded? I painted my tool box with the rustoleum heavy metal primer and then black a long time ago and it turned out pretty good so I bought another quart of the heavy metal primer and a quart of the satin because I just assumed that I would have to prime it with the rusty metal primer first, but after thinking about it Im really wondering if I do have to prime? Help!
