If you are going to spray paint, first, 2 words of caution.
1.) cover up the screw holes near the nuts on the bottom with tape. If you get too much spray paint in them, it will gum up the screws.
2.) spray lightly. some spray paint generates heat as it dries / reacts with plastics, and this can cause your print to melt away.
I would suggest spraying paint on a test print object before committing to spray your refined parts. If you are doing clear, you should spray the insides as well as the outside, as this will increase the clarity by smoothing out imperfections. You don't have to do more than one or two layers on the inside.
A good procedure I have found is to spray 2 fine layers, and let it dry completely. Then I take fine sand paper, and sand the surface. This will smooth out any small imperfections in your print, as well as creating a smooth spray finish. Also, after you sand, I suggest washing the model off with cold water. This will prevent any sand dust staying behind and messing up your next layer. Repeat these steps until you are happy with the surface. Once complete, let it completely dry overnight. Then, I would suggest washing the parts with soap and cold water. spray paint can exude oils that make the plastic sticky. Your final results should look something like these.
