I have the Midway waxed case which has a velour-like lining. Bought it thinking it would do a good job protecting what's inside. I had a rifle in the case in the house at deer camp. It was only in there for 3 days. I had the rifle wiped down in a light film with CLP. I put the rifle in the case and it must have removed the film of CLP on the barrel. When I pulled it out days later, the barrel had already begun to rust.
