First look at the interior of the original Icelandic Dauphin shows that the SAR compartment certainly doesn't have 6 comfortable coach-styled chairs. To keep up with the 'out of the box' premise I decided to simply remove the rear set of 3 chairs, and keep just the front row. It's hard to get rid of the scratch-building habits.
To kick off I decided to try to replicat e the seat texture using Surfacer 500 undercoat (applied by stiff brush), and them dabbing it with stiff wire brush. The effect is satisfactory, but it's just purely academic exercise. The glazing in this model is so thick, that this level of finesse certainly won't be visible.
Inside of the fuselage was slightly sanded to remove injection mould marks, and glazing was glued with Revell's Contacta Clear glue. It's reasonably long drying time, doesn't leave permanent marks if smeared by accident, and dries transparenly. Downside is that it can't be sanded. Edges of glazing were masked with small pieces of Tamiya masking tape, and the rest masked with Maskol masking fluid.
Location marks for the rear set of seats were filled, and sanded. The whole cockpit was primed and painted in uniform gray.
Seats were painted with Tamiya Medium Grey, and highlights were drybrushed with oils (mix of buff and white). Texture and crevices were emphasized using Citadel's black wash (Nuln Oil in gamer's lingo).
