Beginner or expert, the best job can be achieved by covering the entire surface with one piece of film and then adding the additional color(s). But applying MonoKote over MonoKote is not always trouble free. When you apply the second color, rub it down with a finger to get it to stick firmly in place and get out all the wrinkles and bubbles, static cling is your friend. Any wrinkles or bubbles left before you start ironing will only get worse as you work. Keep the heat of your iron absolutely as low as you can go and still have it activate the adhesive, otherwise it will cause the adhesive to outgas and produce huge bubbles everywhere. Start ironing in the center and work out in all directions. You will still wind up with small bubbles but the larger ones can be *****ed with the tip of a new X-acto blade and ironed down from the other edge to push the air out.

Additionally, the conventional wisdom is to lay down the lightest color first and put the darker colors over them as the darker colors will show through the lighter ones. This is especially true of yellow, it doesn't cover underlying layers very well. If your layout has significantly more black than yellow the reverse might work but know that the color of the yellow will be affected.

All of the planes pictured were covered with this technique. The red planes with the diagonal white stripe don't follow the lightest color first rule because of the stripe being less area. On the Epsilon, notice that the color of the wing tip stripes is affected by being laid down over the red/white color line at the leading edge. Again, the small stripe needs the other colors to be laid down first so you have to break the rule here too. But notice that in spite of the large area of the white diagonal stripe and the fact that it passes over multiple ribs, it did lay down flat. This took considerable work prepping by rubbing it down and working out the bubbles and wrinkles but the time spent doing that pays off in the end.
