Personally, I don't use any multiple units cleaning kit - you should do your own research to know what works for you. When it comes to cleaning, Rem oil is about all I use. Tried Hoppe's for a but, which is good for really caked on stuff, but I clean my guns every time I shoot them, and remoil does just fine cleaning and lubricating.
Tho I recently got some renaissance wax for rust protection on some of my blued guns. So far so good, shines them up nicely too
