I am building a Hobbyboss British fleet air arms Hellcat Mk.II. This will be my first attempt at airbrushing a camouflage pattern

I am worried I am going to wreck the model after spending a lot of time building it. Been doing research on technique. My question is was there a consistent way the camo was painted on the real plane? I read on another forum that a paint mask was used on all the planes. Really? every single Hellcat had a similar paint job? not according to my Hobbyboss paint guide

would painting on an random pattern be wrong? Thanks you.
