Basically as the title says, can metallics be used as a glaze/wash?
Essentially I am wanting to give a visor on a model a metallic coppery/bronze sheen to it without covering what I've already painted. But due to the nature of metallics I wasn't sure if that would be feasible and if not do people have suggestions? Please nothing like doing NMM etc I consider myself as barely a beginner at the hobby currently and I will most definitely ruin the model trying more advanced techniques.
