Re: My Volpin Mass Effect Rifle Build
OK, here's what happend; you had a contaminant on it. It could have been oil from your skin, humidity, something the piece was laying on that had wax...something. Yes, you rinsed it off, and without getting to gross, let's just say that water from your tap isn't "pure". Also yes, you sanded it, but the contaminant remains.
NOTE: If you want good water with the least ammount of "things" in it, bring it to a HARD boil on a stove for 3 minutes.
To prevent this there are some easy things to do:
Wax and grease remover, sold in cans in most stores. Apply and remove.
Next use a tack rag, sold in most automotive stores. Wipe down entire part and set part on a CLEAN surface.
Hope this help.
