Outside (glossy side), just wiped it down with naptha (or use charcoal lighter fluid)
first. Paint does not stick great, so use low-tack masking materials. Krylon Fusion
is a good choice as it is made to adhere to plastics, but most sprays seem to work.
I used 5 different brands on this plane. Red, 2 shades of green, white, blue, canopy
was black Solarfilm.
