Hey everyone. I just treated the MF3RS2s and they are amazing. It's so cool how the MF3RS2 responds to the boron - the plastic is quite soft so it takes the boron really well. Some turning has made some tracks in the boron, but there is still a super thin but still fully functional layer of boron on it. I figured out how to polish the outside so it's much darker and interferes less with the color of the plastic. I have yet to sticker this thing up but it's still really great.
