I've only used it pretty much for weathering--like dj above, but used it years ago before the advent of Metallizer, Alclad, etc. to create metal finish on small components. It's good stuff. I've no reason to suspect that it wouldn't work over larger surfaces, except that application would have to be fairly even and consistent for the best finish. I've only seen two colors, silver and gold. Are there any others?
Anthonyandi, experiment with the stuff and let us know how it goes!
And welcome to the forum family! Hope you can find all the answers you need. Enjoy your stay...
