Either get it done professionally or keep your expectations exceedingly low, it's just one of those things.
That's totally not true. I've done a bit of touch-up and repainting work on my old Daytona, and the biggest investment I made was getting a $275 paint gun for $125 because it was a display model. Granted, I was using the air compressor my father already had, but that's about it for equipment.
The real trick is getting good paint and mixing it properly. If you go to AutoZone or some place like that, you'll get shitty grade paint. If, however, you go to an auto parts supplier - the place where the paint shops and dealerships buy
their parts and products - then you can get the good stuff. Most notably, the paint that body shops mix has catalysts in it that will make it dry faster and harder than just the base ever would. This allows you to apply multiple coats in quick succession without waiting a 12 hours or a day for the previous coat to set up. Additionally, going to suppliers or your dealer's paint shop (if they have one), will allow you to get a much better colour match. Of course, the trick with old cars is taking that paint number and then matching it to the faded and aged colour that your car's pain actually is. That was something I never really mastered, but if you're doing something like an entire bumper or side mirror, the little differences in tint and shade aren't as noticeable.
I will certainly say that there is some definite technique involved in painting. Getting the hand motion down, keeping your spray even, making sure that your equipment is working properly (ie. no air bubbles in the spray or you'll get horrible orange peel); it all takes some knowledge, training, and practise. Going into a DIY project at home without professional tools, materials, or training and expecting a professional-grade job is a recipe for depression. But, with some practise and research I think you can get a good result.
Of course, there's no substitute for good preparation. Proper sanding, priming, and cleaning is paramount to getting a good quality paint job. If you skip those steps, the most expensive gear and paint won't make it look any better.
