what to say about Guillow's decals...
I have found them to be too thick to take to the slightest compound curved surfaces, to have insufficient adhesive, to often be in the incorrect scale to the model provided for, to be out of register,
and to be often of incorrect coloration.
The decals provided for the P40 are typical of ALL of that.
I ended up scrapping all but the tail codes - and within an hour of applying them using solva-set and over-spraying with clear lacquer they have silvered...Never Again
The rest of the markings I used on this kit are from my spares folder.
