Here is a random question on Dura-Touch finished firearms such as used by Browning/Winchester. I was perusing Gunbroker last night and came upon a used shotgun in a configuration I have been looking for. This had a dura-touch finish and in the description, the seller indicated "The Duratouch coating has aged and is sticky." It got me thinking because I currently have three shotguns with a duratouch finish. Is this something that I have to look forward to and is a normal aging process for the finish, or did the previous owner use something on the finish that is causing the finish to get sticky, and if so, any idea what that might be?
