Thanks for the comments and encouragement, gentlemen. Louis yes, I have in past builds been heavy handed and snapped the odd thin part. In this case I am being hyper-cautious when snipping and sanding!
Some supplies arrived from BNA Modelworld near Melbourne today (approx 1800km away - The Gold Coast doesn't have a corner hobbyist store)! Some etch from Eduard (only planning to use seatbelts, IP and some of the signage plaques); some 'Mr Paint' lacquer RLM colours; and some Hataka thinners - I have had no luck with thinning their paints, so I have gone for bespoke thinners.
I had already bought some Eduard paint masks for the canopy - and in this particular 'tale of the tape' they won out over the Tamiya masks supplied in the box. This may be personal preference, but being pre-cut and slightly more flexible they they feel more user-friendly.
Interestingly neither Tamiya nor Eduard provide internal masks. I might recycle the Tamiya masks to use them internally, however it seems that the kit is designed to show the external paint through the clear plastic - which may mean painting internal colouring under the camo scheme so that the correct colour is seen internally. I will decide how to approach this once the external masking is done.
In keeping with the general 'unique' feel of the model, some of the windows (I don't think this is a canopy per se) are pre-attached to the fuselage halves. Again this feels delicate and has been handled lightly to avoid my customary clumsiness resulting in damage!
The Eduard masks are going on now, and advice or comments will be gratefully accepted! As you can see I have left on the plastic sprue segment that supports part of the window/door frame - it will be removed when it is time to paint.
