If you've ever been in any factory setting or metal yard you would understand this. Surface rust on bare metal is a non event and typical in any industrial setting. Sorry to break that to you.
Damn dude, you are by far the dumbest person I have ever seen in the world. Surface oxidation, you don't do anything till you are done welding, plating and fastening. The car you drive the engine after cast sat outside in the weather to season it before they bore it out, machine journals, gullies etc... damn know your facts before you open your mouth and prove to us all how ignorant you are
