Let me start off by saying i love mpro to oil all my moveing parts and friction pots and iv been useing it exclusively for about 4-5 years. I dont shoot my ruger vaquero that much as im just not that good with it. I took it to the range last month put 100rds through it. Brought it home broke it down cleaned and wiped it down with the oil. So i took it to the range yesterday same routine but as im cleaning it i noticed rust on the flutes in the cylindervand rust on the side. I love mpro but im the type thats very meticulous when it comes to cleaning. Now i think it could possibly be because i stored it in a soft case insted of the box. But i just lubed it up with clp and let it sit before i wiped it. Was this my error or is mpro not that good?
