So at one time I did work at a gun store. I help prep and hot salt re-blue hundreds of firearms. Final finish always starts with the preparations. It needs to be cleaned. polished, and cleaned again. Some with high nickel content turned purple not blue/black chemistry is the rule.

I have seen nice pic's of people doing their own plating here, maybe you should see what they used.
 
Caswell works great however it’s all in the prep. All parts I’ve had done were using the caswell, so I’d recommend revisiting your prep. Trick is using phosphoric acid after cleaning parts, usually twice dip, rinse.

See photos using caswell. I’d recommend finding a good local shop otherwise you’re stuck shipping…I can think of one or two in California and another in SLC.

Yes, I use the Caswell system. Sometimes I get great results too. However, about 30% of the time I do not get good results. I do not have the experience or time to mess with this process. That is why I am looking at services that do this proffesionally.
