Green Stuff World Chrome Metal paint is the only 'chrome' gold I've found that actually works as advertised. I tried one of those gold Molotow knockoffs and couldn't get it to work at all, and even in user photos in the reviews they never look nearly as good as the listing photos try to make you think they will. Green Stuff World paint is the closest gold I've found to actual chrome and is way more durable than Molotow as well. I'd look up Youtube tutorials on how to apply it though, you have to put it on thicker than normal to really get the chrome effect. I was very pleased with how it worked on this cheap Hasbro headpiece:
