Just finished coating and blow drying my receiver, bolt assembly and all with this stuff. Spent 4 hours cleaning everything before hand as I understand it works by filling in the microscopic gaps in the metal and conditions it, so it's gotta get the cleaning of it's life before hand. What fun. I guess the surface of the metal's smoother, but I'm starting to wonder if you're supposed to use this stuff by itself or if you're supposed to use a normal wet lube on top of it? Also, is it a good idea to run some down the bore?
