It's a decal... you would cut it to an approximate shape to your piece, apply it, and then trim. You would have to apply decal solvent/setting solution to allow the decal to conform to whatever shape you were applying it to.
It tears super easy. Hahaha. I've used it before on a Tamiya motorcycle I built. Have patience and gentle hands, measure twice cut once and use solvent. I liked the look of it for the most part, but I don't how it would look on a large panel.
