Krylon Fusion contains a solvent that etches plastic, that's how it adheres to the slick stuff. It has no benefits over conventional acrylic paints for boolits as far as I can see, but I think there are a lot of products in aerosol cans that do.
I'll even give you one: Amsoil brand "heavy duty metal protector and motorcycle chain lube". Basically a thin version of LLA in a spray can, and it costs about eight bucks for 18 net ounces, and it dries like 45/45/10 making it simple to use and second only to White Label's X-lox in economy.
