Really ? You really need to keep your gun fine all the time.
By the way, back to topic. Just pick up any clear coat like Krylon or other brand, a few code would help you keep the paint but keep in mind that it won't help you stay away from scratch. My gun has scratch every where, it shows how much I used the gun than hanging on the wall.
