If you are going to have automotive paint mixed, it isn't terribly difficult to spray with one of those cheap little "touch up" spray guns. I have used them with pretty good results on a couple of paint jobs. They work just fine with a small compressor.
Of course, if you have no compressor then I guess you won't want to try it.
