So I want on a 50 mile ride on Sunday and hit some hard off road areas as well. About 30 miles was dirt, mud, gravel, grass/weeds, etc... As you can image my bike is pretty dirty and dry. All of the lube in my front shock is dried up and full of dirt as well as my chain.

I'm a gun collector and shooter and I have about two gallons of gun oil/lube. I wanted to know if I could use it to to re-lubricate my front shock and chain. I also wanted to know what you people use and recommend?
