how can achieve the “metal” look on the pack
If you’re talking about doing a “weathered” look you lay down a silver layer and a black layer over it then lightly sand off the black layer until comes off showing the “metal” underneath it.
If you’re talking about making the pack look like the black is a metallic color… either buy a metallic black spray can from an auto parts store or do a light mist of silver metallic over your black painted part.

To weather, what I did was first painted the entire pack black. Then, I purchased a little bottle of model paint, silver. I then got a brush and using reference photos, I lightly applied the silver paint the edges of the shapes on the pack. If you have a box, the outline of the box should be silver. (This is if you are after that look)
Go to the page where I show pics of my pack for an idea of what I did.
if you are after aging the finish to look used and older…
