I am from dry Texas and I bought a VTR 308 with matte finish two weeks ago. I took the gun on a hog hunt to south Texas for two days. The weather was dry with low humidity. When I arrived home, I was going to clean the rifle and I noted a lot of light brown rust on the barrel and on the bolt. Is this common with the matte finish? How do you prevent the rusting? I can not imagine what will happen if you are hunting in a wet climate. Thanks for your comments.
