Would that be similar to traditional (graphite) fireplace black?

I've used that once or twice on various projects and it seems to work rather well.

Thanks for your help and info on this. I'm familiar with some of the BC products but mine are not suited for non-ferrous metals. What store or operation carries that item?

Thanks Franz. Hopefully the BC product is available in smaller containers. Wow.

Great_Bizarro, will the liver of sulfer turn copper black? There add claims that it will 'darken most metals'.

I have used it on brass & copper, it turns it a matt black. You might be able to clear coat with a gloss clear and get a gloss finish, but I haven't tried that. It has a chemical reaction with the copper so the copper must be very clean and free of oils. You put the chunk of liver of sulfur in hot water and watch as it turns black. Works great on pennies.
