Dude, painting is easy! Start with a simple paint scheme like running a piece of tape diagnaly down the side. From like the top of the rear corner by the spoler, then towards the front to the bottom of the body right behind the front wheel. After you make that one piece of masking tape even on both sides, tape off the rest of the lower half. Now paint your main color, Make sure your windows are masked! Do a nice brite color like yellow or something, it's easier to see your car that way. Let it dry (15 min.) pull off your tape and do one more color. or remove the tape and tape a different portion that hasn't been painted yet so you sill end up with a three color scheme. If you do the light color first, just be sure to back it with white so the other colors won't blead through. Do like Yellow, orange and Black.
After you do an easy paint scheme, you can try and get more elaberate on your next one, because there is ALWAYS a next one!
