Phicen bodies are made of silicone. What that means is traditional paint doesn't really stick. One of the reasons silicone molds work so well it has its own natural release properties.
Only silicone sticks to silicone so silicone paint is actually tinted pre cured silicone that has been diluted. It basically cures to the surface. Think epoxy. I dont know of any chrome/silver way to paint silicone. But google and look. Maybe something outthere.
