I found a place online and went there this morning. I returned the Duplicolor and bought some Omni paint (single stage). Just a quart for now, but I'm going to just to the door jams and inside the trunk to start. He said that if my current paint is fully cured and in good condition then I don't need to prime first... does that sound right?
Technically, Yes. If the paint you have is good you just need to sand it and paint over it.
However, if you have the original paint on the car it is probably lacquer and that is not a good foundation for new paint. If it is a fairly recent repaint with a catalyzed product, sand and paint over it.
You also may not know what is under the existing paint. Poor bodywork, rust starting etc. I have NEVER been disappointed that I took a car to bare metal. I have often been surprised at what I found and glad I did.
Stripping the car is alot of work and not for everyone and not every car needs stripping. I just want you to understand that there is some risk involved in painting over the unknown.
It is a decision you have to make. Make sure the condition of the existing paint and bodywork is exactly how you want it, if you paint over it. It won't hide anything such as waves, bubbles etc.
