Hey D.
For my Formsa, I used plastic model paint. Works a treat and hard to scratch.
Or any acrylic paint will do. I brushed ine, but if you have an airbrush, that works also very well (did that on my GWS P40, same as the Formosa, with plastic model paint (Humbrol Enamel for me))
Great little model, one of the best sport electric model I ever had !
Oh, and by the way, just in case, if you need it one day, I have a complete wing in my garage f you need some spare (the one on the photo :oops: )
