  Decals Details Diorama Dry Brushing  


In principle a thin film with a printed image on one side and water soluable glue on the other. How well decals adhere to the surface depends on flexibility of the film, quality and age of the glue and last not least texture of the surface to which the decal is to be applied. - And here the problems begin. Non specular paint  is rough like a field of pebbles. The decal film lies on top of each pebble and therefore there are a lot of gaps where the glue doesn't stick.  The  result is not a painted-on appearance but something with a silvery surround. Decal softeners help a little, but not too much. The glue of the decal must completely cover the surface. It can do this if the underlying surface is as smooth as a sheet of glass.


Use paint of high gloss and apply a coat of semi matt paint after the decal has dried. If glossy paint isn't available bring it to a glassy sheen by overspraying with transparent laquer (caution: both kinds of paint have to go together).



Details make a model more realistic, giving it a convincing look. Real details are found on the real stuff (or photos of it) the others in model magazines (especially German ones).


Real Details:


fictious Details:

Wing profiles can be concave (inwards bulging).
Thin trailing edges on wings, elevators and rudder
Thin and slightly twisted propeller blades
Thin pitot tubes
Thin landing gear covers
Thin clamps on landing gear legs
Compressed undercarriage when aircraft is on the ground (and split u/c covers on certain a/c)
Transparent navigation and landing lights
Thin canopy glass
Canopy rails for sliding canopies
Flush cockpit glazing on modern aircraft and many WW II types
Seal between fixed and opening part of canopy
Open ends on exhaust tubes
Downlead on wire antennas stretching between masts
Thin sheet metal seat walls
Thin upper ejection seat handles
Spiralled (not segmented) stripes on upper ejection seat handles
Seat belts and parachute straps not just single strips
Sheet metal behind engine hood protrudes at rear in case of F4F/FM, F6F and TBF/TBM
Trenches ("sheet metal joints") while the original had overlapping sheets. (many WW II aircraft)
Distinctly protruding cockpit frames (excluding some early WW II types)
Exaggerated ageing and weathering
Narrow black stripes behind wing guns
Bad Japanese paint
Chipped paint on US carrier aircraft
Non existent panel joints highlighted with black paint
Bare metal spots where nobody walks or touches
Bare metal on wooden parts
Sagging textile covering
"Textile structure"
Removed service panels on the floor around the aircraft
Everything open to show the inside
Open bomb bay on WW II carrier aircraft with spread wings (takeoff to follow)
Open dive brakes on the ground (exept F3H)
Radial engines with chrome cylinders

The left column should be self explanatory (at least I think so). If in doubt, check photos. None of the "details" on the right side are/were found on real airplanes (even tanks don't show bare metal on every edge).

Before applying any of these spurious details T H I N K !

Is that what I intend to do possible? - And if yes, can I reproduce it in scale?

In my opinion a model is a good one when in a photo it can't be distinguished from the real airplane.  The most important point here are sharp trailing edges. Especially in 1/72 quite a few  models are disfugured by blunt trailing edges.  But also in larger scales sharp trailing edges aren't common. all the effort to superdetail a model is wasted when thick rounded edges on rudders and so on reveal the model at once. The manufacturers can't be blamed for this. The form needs to tell the liquid plastic where to stop.

For another exaggeration manufacturers are as responsible as modellers: Overdetailing. A kit not showing a multitude of grooves gets a bad press for lack of detail. Because lines the plan shows are missing. Here the question arises: Lack of detail in the kit or overdetailed/wrong plan? There are two kinds of plans: The blueprint in the factory and the drawing from a graphic artist. Apart from almost usual omissions or mistakes the latter shows the external appearance of construction details as lines.  The toolmaker (not necessarily an aircraft expert) now engraves these lines into the mould. Take for instance a Me (Bf-) 109. In kits you see vertical grooves behind the cockpit. Obviously panel joints. In reality not a single groove was to be seen (see page P, panel joints). This part of the bird - like in many other types in WW II, especially American ones - was manufactured by overlapping segments. In the 1/48 kits of the Tamiyas F4F/FM Wildcat and the Hasegawas F6F Hellcat, both manufacturers  depict  these vertical segments verly clearly as steps,  As the thickness of the original metal sheet was in the range of 0,6 to 0,8 millimeters, it can't be depicted in 1/48 or less. In short: Grossly overdone!

Most wartime planes were manufactured by riveting overlapping panels to internal bulkheads and stringers. So gaps were only to be seen around doors, service panels or different structural members (rudder, ailerons, cowling and so on). As the laminar flow wing of the P-51 was very sensitive to flow distortion North American sealed every panel joint with putty and if not painted Olive Drab anyway  gave the whole wing an overspray with aluminum color. "Highlighting" such non existent panel lines may show your painting skills but not your knowledge of the real thing. Due to the high speed of modern aircraft gaps have to be kept to a minimum. Otherwise the plane would disintegrate in flight. In general panel lines in kits are as wide as in the original. Grossly overdone. In my opinion in 1/72 a model without such grooves is more convincing than one with them.

To cure exaggerated grooves they have to be filled with putty (slightly thinned with liquid plastic cement), sanded smooth and rescribed with the tip of a scalpel or a needle if actually needed. Use of templates can be helpful. Another and very convincing way is to use a hard sharp pointed pencil for outlining all details after the model has been painted (naturally after all grooves have been filled and sanded smooth).

Not to forget sizeable rings on landing gears, especially in 1/72. In reality they were thin metal strips fixing the gear covers. The latter invariably were also of (thin) external metal sheet with some reinforcement structure welded or bolted to the inside. Again moulding restrictions are to be taken in consideration. Therefore collecting thin plastic from wherever you get it is highly recommended.

Japanese paint was of very high quality. Unfortunately, it is often overlooked that Japan had two air forces (Army and Navy) and bare metal was intentional in the former case (see page J).

Pacific war: The often cited hot tropical sun in the Pacific had less influence than one might think. Most often, the Navy's brighter paint scheme during the early days is thought to have faded (see Colors on The US Navy 1941-1945). Navy aircraft with geometric markings on the vertical stabilizer were not stationed on islands, and those of the Marine Corps were not stationed on aircraft carriers until the fall of 1944. Scuffed areas at best on the bends of F4U Corsairs. Excluded on aircraft carriers for corrosion protection reasons. Incidentally, service time in the Marine Corps was about 6 months, sometimes only weeks for shipboard units. No chance for aging!

To bleach paint it takes a lot of time. Not all paints detoriate the same way. In every case: Did the aircraft "live" long enough? And was the aircraft actually exposed to so much sun and heat?

 In any case before applying paint see also page A, "Ageing"



Miniature still life. A real situation depicted in model form. Makes models interesting for girl friends, mothers-in-law, wifes and other natural enemies of modeling.

Miniature figurines help a lot, but only so if they show a good paint job.

The situation though fictious should depict a moment in real life. Its therefore absolutely necessary to know what the real life looked like.

Beware of propaganda photos! Mission briefings are not held in front of some aircraft, and leisurely chats with the mechanic are very scarce when enemy aircraft have to be intercepted. Equally so after landing. The deck of an aircraft carrier is crowded, windy, loud and dangerous. Nobody in sane mind would be there longer than necessary (Absolutely no chats!).

Remember also that servicing an aircraft doesn't require to strip it down to the bones. An oil check doesn't require to open the panel for the elevator trim. And if a panel is removed it isn't placed on the floor (you'd step on it sooner or later). And tools are kept in the toolbox (in contrary to Mr. Verlinden's opinion).

Well, I know such scenes are to be seen in many modelers magazines. Therefore these lines. - Think before beginning.


Dry Brushing:

"Dry brushing" was invented by Francois Verlinden, a Belgian, for accentuating edges on tanks.. By no means did he want to show paint scraped down to the metal, but only a delicate touch that would merely suggest the metal.
His method consisted of using a soft brush of the best quality (i.e. expensive) to rub off the paint, in this case steel, picked up only with the tip of the brush, on a soft cloth until nothing was visible. In fact, tiny traces had remained, which he now spread with gentle movement over the edge. Which required some practice as a result.

If you use a brush with coarse bristles, you don't get a delicate gradient of paint, but coarse stripes.

If the paint is too dry, you get a sandy relief, if it is too wet, you smear the paint.
The biggest mistake, however, is overdoing it.

After dry painting seemed too complicated and error-prone, I tried alternatives that were easier to use but still convincing in their effect:

Spray the slightly lighter color vertically next to the model from above using an airbrush. The barely visible edge of the paint mist is enough to make the desired part appear lighter at the top.

Second method: paint/spray the model in the desired color. After the color has dried, paint/spray over it slightly darker. Allow to dry briefly (not completely!) and then wipe off from top to bottom with a cloth moistened with thinner. This will bring out the original lighter areas, and the darker color will remain in the recessed areas.

In both cases, it will be advisable to cover or mask other areas beforehand.
