Step 1: Clean the Gun
If you're going to do something, it's worth doing right. When it comes to installing GunSkins, it's important to know that longevity and quality depend on how well the clean and prep the surface from the get go. Rubbing your gun down with alcohol sounds like a good idea, but it's not going to as effective than if you used a gun-specific degreaser.
Spray the surface and scrub with a small brush so that all dirt and grime buildup is removed. Keep in mind the texture on the stock and pump action. Wherever you intend to wrap is a good candidate for a thoroughly cleaning. Wipe down with a lint-free cloth or air dry before moving on to the next step.
Step 2: Peel and Stick
Disassembling the weapon is optional. The vinyl kit is designed to be installed on a fully assembled shotgun, but some prefer to do it in pieces. Each component of the kit is labeled to its corresponding surface: buttstock, forend, receiver, and barrel. Select one and peel the vinyl off the backing, centering it on the gun.
Use your hands and fingers to work the material. We suggest starting in the middle and working outward. If a wrinkle occurs or you are not centered, simply peel the piece back up and try again until you are satisfied with how it looks. The vinyl is very forgiving and it won't loose adhesion during handling.
Step 3: Heat and Trim
Shotguns come is many shapes and sizes. The kit is universal and will require a sharp hobby knife to trim to fit. Install the vinyl so that it overlaps across the top and bottom of the stock and trim away any excess. Other areas to consider trimming away include the trigger guard, ejection port, and the butt pad. When installing on the barrel, we recommend placing the piece centered on top and wrapping around. It is not necessary for the two pieces to overlap on the barrel when it meets the receiver since this will not be visible when the gun is operational.
Use a heat gun or blow dryer on the vinyl ot make it malleable. This is helpful when pressing the material into the surface to reveal the texture and other detail. While warm, the vinyl is also able to stretch and conform to the shape as you need it to. For example, where the buttstock meets the receiver will require heavy use of heat and strecthing to make the material conform to the drastic angles and curved surface.
It's important to take your time and work out the details as you go. Finish one piece before moving on the next. Once everything is installed, oncinute running the heat gun up and down the entire weapon for ten minutes, pressing in with your fingers. This post-heat process sets the material for maximum adhesion and keeps it looking good for the long haul. Once cool, the gun is ready for action!
