RedRock,
Based on my limited experience:
1. If you plan to use different colors of spray paint on large and small areas of the engine, I prefer to tape off (cover up) the large areas first, and spray the small areas first. If you paint the large areas first, then you are going to have to put alot of tape over alot of new paint when you tape the big areas off to paint the small areas second.
2. When you spray paint, spray with the can 14 inches back from the model, and never point the nozzle straight at (90 degrees to) the model. Very light gentle swishes from side to side, like you are just dusting it with paint, with the nozzle slanted slightly away from the direction in which you are moving the can.
3. Spray three very light coats. Let them dry thoroughly, at least a day between coats. If you spray the paint on too thick, then it will run and "fill in" all of the small details, like the rivet heads, board creases, etc. etc. All of the detail is lost.
4. Before you paint, make sure the can is at room temperature, and shake it a full minute before spraying.
5. Open the danged window before you spray!!!
Hope this helps.
