AP1's black oxide

Hi everyone, new to this forum but have to say loving it so far!   Was just curious if anyone ever done this to AP1's or 2's??  Black oxide (gun blue).  Was interesting in seeing a photo and how well its holding up.  Thanks!

I have never seen black oxide ap1/ap2, but I have seen black oxide MB's. I just saw some on Ebay, if you look quick you might find them

Well I went ahead and ordered a kit anyway.  I'll post some pics up when its done, hoping they look good enough anyway.
