I have been using this source for my gun wrap for many years. Rich In Michigan turned me on to this 1080 3m exterior graphic years ago. Easy install other than making good square cuts. Protects the bluing and will not harm it. Makes for a good dress or protective cover. Many choices of brands, designs and colors. Super adhesion and most brands are non bubble capture by design.
FANG APPROVED!
