Re: GOTG: My own Star-Lord Build
Kevin said it. It comes in little tubes, like the tiny toothpaste size you get at the dentist. It's a liquidy paste that's essentially a wax/glue that's been mixed with silver leaf. It turns whatever you rub it on silver. Like Kevin said, if you apply a solid coat of it and buff it like you were shining a shoe, you will get a very shiny metal finish. To get a worn down look, I first paint the subject black. Then using an applicator (I used the rough inside of an old sock) that has an uneven texture, I lightly sweep the rub n buff across the surface in a single direction, slowly building up the silver. Too much and it will get too shiny. Going slow allows you to control how shiny it gets. Allowing the black underneath to show through gives you the aged look.
After a few hours it will dry in place and you're good to go.
