Here is a short tutorial that shows you the basic steps necessary to apply decals to a plastic model airplane:
To apply decals to a plastic model airplane you will need:
Decal Setting Solution
Pre-cut the decals using scissors or a hobby knife.
One at a time, dip a decal in water for a few seconds until you feel the decal move slightly from the backing paper.
Using a brush apply some setting solution to the area of the model where you are planning to put a decal.
Slide off the decal from the backing paper as you position it on the model.
Using a brush apply more setting solution on top of the decal. Be very careful not to move it while you apply it. Allow the decal to dry. Carefully remove excess setting solution and water from the surface of the model using a tissue paper.
If the surface has many irregularities, like panel lines; you may need to add additional applications of setting solution.
If you see bubbles appear on the decal, you can pick them with a needle or with the point of a hobby knife and then apply setting solution with a brush until the bubble is flattened.
This Monogram 1:48 scale model kit of the Boeing B-29 Superfortress was modified to include 4 electric motors, internal lights, navigation lights on the wings, blinking tail light, front tire light and a light under the fuselage.
The surface of the model was painted to resemble a metallic surface. Some areas were covered with aluminum foil.
I developed this technique a few years ago when I was trying to find an easy way to delineate panel lines on my plastic model airplanes. The results of using a pencil are quite good. It works best with a flat/dull surface. You need to use a well sharpened #2 pencil (or a different grade, depending on your taste). Carefully and slowly trace the panel lines of your model, blowing air with your mouth as you trace the lines to help remove the excess graphite from the surface of the model.
Applying a coat of dull or glossy clear lacquer
When you are finished delineating your model, apply a coat of dull or glossy clear lacquer to help seal the graphite to the surface of the model plane.The results are fantastic.
I just published 4 new galleries from my collection of scale model aircraft. The new pictures have been taken in new diorama setups. These models are all in scale 1:72 and include:
Messerschmitt BF-109K in scale 1:72 (Germany)
North American T-6G Texan in scale 1:72 (US)
North American P-51 Mustang in scale 1:72 (US)
Dassault Mirage 2000DP in scale 1:72 (Peru)
On this post you can see a sample from these galleries. A P-51 Mustang long-range, single seat fighter aircraft used during World War II by the allied Air Forces. Go to the “Examples” section to view the complete galleries.
