10-15 years ago I would have never thought I'd be hunting with a Camo Gun...but now I almost don't feel comfortable Waterfowling using anything but. I have a Remington 870 Special Purpose that must be 7-8 years old and it looks and works A1, bought a new Extrema 2 last year and it is hands down one of the best purchases I have ever made.
The camo finish on both of my guns is very durable and makes the gun pretty much weather proof; Salt Marshes and Potato Fields in prime Duck and Goose hunting Weather will make you a believer of a coated gun.
Don't get me wrong I love my polished blued, walnut stocked shotguns...more so on a nice sunny day walking through the woods looking for grouse and rabbits though.
Couple cell phone pics of from last fall:
