[Healeys] Tool Black ?

[john spaur]

I am using Caswell's black chromate on small parts.You need to zinc 
plate the part first. The research I have done on gun blueing show 
there is a hot and cold process. The cold blueing is not very 
durable. I have not found any hot blueing kits and the process is 
very toxic compared to the cold process. Black chromate is very toxic too.
