Clean the metal so there is no residual oils or lubricant. I simply wet a patch with Gunscrubber to wipe and clean the exterior.

Light application is just a few drops on a patch. Not soaking wet. You just want a light film to cover the metal so it gets dry.

Here is a video clip on YouTube that is a good tutorial on Ezzox to help answer your questions. http://www.youtube.com/watch?v=lFn8wrUPMZ0
