I have two handguns with brass grip frames. I will clean them up all nice and pretty with Flitz but what will keep them that nice bright finish?

Wax

More Flitz
Seriously don't know what else

Let it develop that nice patina, much better than the bright shiny look IMHO.

Renaissance Wax?

Thanks.

Amen,...preach it, Terry.

DGW once had a treatment called "Old Mustard",....once alla' that Italian Lacquer was removed, one could get there quick, and that patina is one tough finish.

I've got a 1866 Henry by Navy Arms that I'm painstakingly letting develop it's own patina. It's hard because the neglect on my part is particularly foreign as it goes against everything I've ever learned about caring for firearms. However, I'll just keep moving along.......after all, the rifle does have that ugly European walnut for stocks.

The rifle is a .38 spec and shoots extremely well!

That patina can be developed very quickly if you clean the brass, then apply chlorine bleach with a rag to the brass.

It makes a very nice patina.

Polishing brass to keep that new, shiny look is tiresome. I like the patina better.
