Great advice from Gibbs/NCIS. Paint that thing!!
Film is great when weight and finishing speed are key. In my opinion, painting a plane gives you much more opportunity to make it perfect vs "what you see is what you get" with film... I still use film for some planes, but have really shifted toward fiberglass or a fabric with paint (koverall is a good choice as well as the Solartex). Pardon the ignorance, but are you planning on the Chimpunk color scheme with lots of red stripes on the wings & so on?? Lots of seams with film! Seams in film are a real bummer... They are just "there" to begin with & then they always seem to collect gunk, get snagged by the cleaning rag, etc. Applying clear to the seams can help but isn't as sure a bet as paint. You might even try latex for the colors & then of course clear over this with ideally an automotive 2-part clear as this is one of the very few types of clear which will not yellow over time. If a flat is needed, PPG DCU2026 mixed with regular clear will create anything from a slight satin to an eerily dead flat depending on the mix. I've used latex & clear on two planes now, a B-17 (over glass) and a SE5a (over Koverall).
good luck!
