Thanks to everyone who replied to my request for help. I found a supplier here in the U.S. that carries XtraColor paint, so I was able to obtain the RAF Blue Gray for the fuselage. Color photos of the Wessex I want to do shows gloss red in the hi vis areas, so I'll use red instead of international orange or dayglo orange. I have always had problems applying dayglo colors and they seem to be very fragile once on the model. Thanks again from Texas!
