I don’t know how Lindy gets the gold onto the fireball jigs but I’m thinking it might be plated on? Anybody know? Reason I say this is that the hook is generally so thick it takes a lot of sharpening to get the stuff off and make the jig any good. Consistent with what James said, I have gotten shiny gold at the hobby stores here in town, those that sell kit cars, trains, etc. I also believe Netcraft sells it in small quantities.
