Hobby Black's active ingredient is the poison selinium dioxide.
You might be able to find it, or similar chemicals, at a gun shop.

I used Hobby Black many years ago and dont recall any chipping or flaking. I worked in a factory that used a similar chemical coloring process referred to as "Black Oxide" finish. This chemically etches the the surfaces and adheres to the metal. I am wondering if the chipping you refer too may actually be a spot where the metal surfacre may not have been 100% clean and the process didn't make the bond.
