Hello,
I have been trying to make a good quality decal for my restored ww2 German m40 helmet.
I would like your opinions on what you think of my decals.

I have been experimenting with the best way to make them and here is what I have come up with.
They are plastic like decals that will have to be stuck on with an adhesive to a helmet.

They do not wipe off or tear easily, below is a demonstration of sandpaper being used to test the strength.
I decided to test one by scratching it with sandpaper.

It ended up tearing from the force of the sandpaper being vigorously rubbed up against it, but the decal color/outline stays
