I applied a black wash on the parts (preceded by a coat of gloss /Klir).The wash is very light here because the goal is not to dirty the ship, but just to highlight the details.

(sorry, no photos)

There are a bunch of decals. They all need to be cut from the board and are quite fragile, and many will lose a little of color in the operation. Cutting small black circles is made with a punch ... with more or less success.

I damaged one of the large striped decal strips that circling the dorsal tanks. So I had to redone the damaged part with paint.
To hide the difference, I made a small black weathering with the airbrush to simulate a dirt panel.

It remained to apply a coat of varnish before final assembly.

I tested the Microscale Micro Satin (thinned with water), and as I did not see any differences after drying, I went to the Micro Flat ...not better!

So I get back to Prince August Air mat, strongly mixed with Tamiya thinner (with proportions around 10/90) and especially not with alcohol, to prevent white marks.
