If your FB was post 1959, they are a little trickier to take a part; just like the slims. I have a slim I am thinking of sending in for CeraKote for a test. (Imitation is the sincerest form of flattery). I was thinking "Satin Mag", "Titanium" or "Ridgeway Blue". The tactical black is very very nice though.
The color is a satin black. I think all fatboys before and including 1960 can be taken apart easily. The guy who did it was not a wet shaver but he did great job.
I'm not going to quote my post, as it would be like posting it again. I will just apologize. Won't happen again.
