If you go to an automotive paint store, they mix up an OEM color in any brand of paint you want and put two part (paint/catalyst) automotive paint into a rattle can for you.
If you want two stage base/clear you can buy the two stage system with a can of color and a can of clear. It's not the cheapest thing but it's very easy to use you don't need a spray gun or compressor or anything.
The cans have a push button on the bottom that release the catalyst inside the can, once you press it and shake it you have a few hours to use the can up before the paint is no longer usable from the can. the store I've done this at gives a core charge on the can as well if you come back for a refill.
