Hi Kev,
I used white profilm for the wings and a Hobby King red for the fuselage. As you say, they are a bit shiny, but when the model is in the air, you hardly notice.
I also built a 1/4 sc version and covered it with Solartex (unfortunately now no longer available). You can see this model on p6 of Scale, my one is blue and yellow and another one by Kieran Wallace which is red and white.
Best of luck with your model, don’t forget to post photos and keep us up to date.
Regards, Gerry Buckley
