I didn't use spray paint on my first paint job. Problem with spray paint is, unless your really good, and I mean real good, it'll be obvious it was done with a spray can and by the time your done buying all the cans of primer and paint, you could have just bought the materials and used a spray gun.
The hard part with black is that you have to do a lot of body prep before hand. If you have any slight imperfections in your body work, the black paint job will make a dent, scratch, or wave in the body look 5 times worse. That is unless you plan on spending a couple weeks doing body work and using the correct grades of sandpaper and use filler on ALL the little dents on the car. Trust me, I spent a couple weeks doing the body work on my car, and I still had a small dent on the roof and a small one just behind the drivers door. Since then I had those fixed.
Yes my dad and I did both paint jobs on the car. The first one was just catastrophe cause we were living in mississippi. Bugs were constantly flying towards the paint so I was have to swat bugs while my dad was shooting paint. BTW we did both paint jobs outside. Laid down a tarp on the side of the house for the second paint job so no dirt would kick up. Not too shabby eh lol.
If you want to test the whole spray can idea, I would definately like to see how far you get. I've never personally tried it, but have heard of it working once before. Any other time I've seen it, the owner wished he had just used a spray gun instead. Luckily my old man knows how to mix the chemicals together to shoot while I mainly do all the body work and use the spray gun. If you can do all that on your own, the car is your canvas. You can do WHATEVER you want. I wanted my malibu to look like it was from the 60's instead of the 80's , which unfortunately the first paint job didn't give me.
As for the wheels, that was my old man's personal touch. The rims were going to be painted to match the paintjob anyway, but I told him to paint them solid gun metal gray just to make it easier cause I had to head off to school. He did that whole two tone rim idea while I was at school and I'm glad he did. The red sets off the rim so you can actually see the curves.
