Back in November 2013 I sprayed my Wingmaster with a shake n spray kit from Duracoat http://www.lauerweaponry.com/index.cfm?fuseaction=category.display&category_id=929 I got the stuff from Germany not the one in the link by the way.
Since I started that topic about me spraying the gun with duracoat I've been regularly messaged how's it holding up so I've taken a few pictures today to show you all the results so far.
The only ware to the finish is on the magazine tube and it's only ever so slight as you would expect from a pump action
