I recently purchased and M&P 40 and the slide is coated in the new EXO finish. I know little about this finish and the website tell me little of how to care for this finish. What I'm wondering is if its safe to use my standard cleaning products on this finish. Can I use a lead free cloth on it? I'm addressing this post to anyone who might be more frimiliar or have a gun with this same finish that can enlighten me a bit. Thanks!
