Nice work on the FW24. I completed mine about 9 months ago. A few tips:
make sure your blue/white transition is smooth as although the silver decal is wide it is very thin and shows the line underneath(I speak from experience). Also dont forget that the front wing side fences are blue and black (leave them separate for painting).
Oh, and there are black CF areas where the exhaust comes out!
The rear cowling didnt fit properly on my model either so double check it now before its painted and decalled!
All the very best with what is turning out to be a fantastic model.
