Thanks guys. At the moment Geo, my first choice is the White 16 above for the mismatched cowl but I won't need to decide til later.
I started (guess where?) in the cockpit by first stripping the paint. A short dip in Windex dissolved it quite easily.
The housing for the Mk108 cannon provided in the kit is the wrong shape, being a legacy of the G models that the kit is based on. Though a corrected sidewall and other parts are provided, Hasegawa didn't change this detail. I started rounding the butt end on its own but when I dry-fitted it to the rest of the housing, it became apparent that much more will be needed.
I've since built up the shape with card and CA, filled and primed it, and will show it when I'm done. While that's drying, I moved on to the lower wing where some mods are needed. The moulded vent detail between the wheel wells needs to be filled in (I used two gobs of Tamiya grey surface primer) and a new ejection chute for the 30mm shells needs to be cut in, which I've not done yet. The wheel wells come round and need to be shaved to the angular type, one of which can be seen at right below.
I was thinking of giving riveting a try and before I could change my mind, I launched into it and finished the port side of the fuselage. Hard to see in the below pic but it's there:
Thanks for looking.
