Are you sure these will fit to the model?
Harry the painting in general is the last thing we do making a model. The simply example ...you started painting of the undersides of the Ju-87, right? But you haven't attached these wheel spats.There will be gaps between the wheel spats and the wing slots for this. So you will have to use a putty, then sanding, then polishing and fianlly painting.
1. Apllying a putty you can damage the painted areas.
2. Sanding the putty and polishing you will damamge the painted areas for sure.
3. You will have to paint the areas again and as a result you will get two coats instead of one layer of the paint.Details at these areas will become less seen.
Can you see here any advantages? I can't
