Alright. Here's my first attempt. The key here is to use a very light colored watch, like white or light gray. That way the film will show up.
And this is very durable. Since I used a light color resin I didn't spray any type of base coat, which solves the "bending paint issue".
Not too bad for my first shot. My next one will be way better since I know what to do now.
So I went with a navy type camo, and it started separating a little because I couldn't get a good grip on the resins quick enough. I know how to solve that one now.
Here are some shots. Came out pretty unique looking:
