When we met with Good groupers bunch we spoke of the coppermelt affecting steel. One of the guys said that they applied coppermelt to gunsteel (4140 and stainless I think) for a period of time and saw no sign of discoloration or damage.
Maybe we can get whomever did the test to fill us in on the particulars of what they did and for how long.

Absolutely. After all, I am here to help and I should because, save Roland, I have had more experience with this product than anyone on here so I will try my best to explain what we did.
Roland and I both performed our own seperate experiments of Coppermelt at our first encounter with it. We each had a piece of barrel that had been cut off from one of our earlier projects. Mine was a Pac-nor stainless steel chunk and I forget what his was-maybe a chunk of SHilen. We then dropped several drops onto the barrel steel and let it sit for 1-2 nights. We also dropped some onto bullets for the same duration. After the time was up, neither steel had ANY discoloration of any kind. The bullets on the other hand had a thick coppery goo that had sluffed off from the tip down. We then decided at that point that it was safe enough to run in our custom barrels and the rest is history. After over a year for I and over 18 months for Roland, we are both still using and loving the stuff with <font color="red"> ABSOLUTELY </font> no harm to any of our rifles. The stuff just plain works, and believe you me, there are many companies investing all kinds of money trying to figure out HOW this stuff works but none have succeeded so far. They know what is in it from a chemical makeup diagnostic, but they can't figure out the process of incubations.
