Sidearms & Scatterguns Off the Wall Q?

Friend of mine asked me if having a black powder (Ball & cap) revolver coated in NP#3(ROBAR Finish) was a good idea ? Have no info/history to pass on so I thought to present it here.
It's not a SS Ruger Old Army so I can't suggest just cleaning in hot soapy water. Anyone familiar with b&c revolvers & the cleaning of such ?
Thanks

With the new generation of black powder substitutes that don't rust the steel like the original did or leave the caked on residue, whatever coating he wants to use should be okay. Cleaning is so much simpler. If he wants to use real black powder, I'd recommend the hard chrome. Soap and water clean up and a hair dryer to take care of the water. JMHO
