From another Site... Wrapping up firearms for shipping generally includes some type of packing material, a container, and some type of cushioning material like old newspapers or more often bubble wrap. There have been a number of posts on mysterious “spots” on both stocks and barrels. No pics until now though. At least none that I have seen. Courtesy of one of the RFC members via an email to me, we do have pictures of a severe case of the “spots”. Here they are: This is a custom made ammunition box that “our” guy had made. Made out of aromatic Cedar and has been finished. The box was wrapped in bubble wrap, then in a cardboard box. The spots that you see are from the bubbles in the bubble wrap. Bubble wrap has to have some type of what I am going to call “release agent” on it to make sure it does not stick during the manufacturing process. These can be a variety of chemicals, most of which can harm a translucent topcoat and in many cases the bluing on a barrel etc. as well as other stuff. Seen some on ceramics also. These chemicals need to be removed and in the manufacturing processes used in the U.S. they are and that is done very well. Unfortunately we cannot compete with overseas manufacturers from a cost standpoint and one of the results of that is less quality for less money. If the rinse cycle is not a quality process, some of the chemicals will remain on the plastic. Been a couple of posts about this but like I said no pics until now. When the chemicals remain on the wrap, you get the above. Anybody getting a firearm shipped to them or shipping one should make sure that the firearm is wrapped first in “brown” paper, not newspaper and then in the cushioning material. Fortunately our firearms manufacturers do that.
