To check for any surface irregularities, the nose and fuselage are given a light grey coat of grey. I used MR.HOBBY GUNZE SANGYO acrylic #306 acrylic. The interior was masked to protect the already painted interior. 

The next step is to apply rivet details as the Revell model is far to clean. On a real Lynx various rivets are clearly seen. Typical for most helicopters. 

For the raised rivets, a new type of after market set was used. MICRO-MARK USA has, for railway modelling, decals set #84985  with resin raised rivets! This is new to me, I think these type of rivets have only recently become available.
The rivets are printed in rows on the decal. So each line is cut with the rivets and applied to the model. Many, many are needed on this Lynx in 1/32 scale.

The rivets were also applied to the rear areas like the tailboom and tailrotor fin.

Once the rivet decals were dry, another coat of light grey paint was airbrushed. This seals the decals and ensures an even sheen. 
The result looks great and vastly improves the realism to this model. 
 

PAINTING THE SH-14D MODEL 

For the enamel paints Extra Dark Sea Grey XTRACOLOR X-5 or X-376 of HUMBROL 123 enamel can be used. I used acrylic  from GUNZE SANGYO H333  .
....
For the Sky enamels XTRACOLOR X-607 enamel or HUMBROL 90 enamel or White Ensign Model WEM ACRN01 Sky can be used. I used the WEM paint. 

Note also the tiny raised rivets added to the model

The tailboom with the new hinge details and rivets added.

The black anti-glare panel was also masked on the nose and airbrushed matt black.

The yellow tail warning panel was airbrushed MR.HOBBY GUNZE SANGYO Yellow H329 acrylic.

The rotorblades are dark green (Sikkens 46056), for which I used GUNZE SANGYO #340 acrylic. The new BERP main blades also have a metal leading edges. A lot of masking was needed here before applying REVELL Aluminium acrylic 36199 to the edge. 

After drying, the overall model was ready to get its markings with the decals. This is done now as the model is easier handled at this stage. 

Engine

As noted before, some extra detail was added to the model, particularly on opened up engine bay and engine and an opened access panel at the main rotor gear box.

After completion, various paints of metal, copper and aluminium were applied. The red air oil cooler fan intake sealing is also seen. 
The side hatch with walking area was also detailled. 

Next step is applying the markings.
