Yes these are nice. But do you remeber the problem with D-day strips? I would suggest painting a piece of the model sprue with the silver and let it dry for a few days. Then applying the blue one.Check if it is possible to apply the blue paint on the silver without any reaction between them.
Very nice H! As for the silver vs blue, that was earlier talked about, I painted the red and the green first on my two Mustangs...seems to work that way too, no reaction.
