The process of applying DuraCoat is not much more difficult than painting a lawn chair with spray paint. The biggest difference is that DuraCoat is a resin and you must mix it with the supplied hardener before spraying it on your weapon, or with DuraBake you have to bake the weapon up to temperature to cure.

Duracoat should only be applied indoors in a garage or similar building with good ventilation or outdoors and never in the home. Masks, N-95 paper filter type are always recommended as minimum protection with good ventilation. Always wear safety goggles when working with any chemicals.

DuraCoat will react with any uncured Silicone near your project.
Even Silicone in a sealed tube across the room can cause a reaction. Usually it causes bubbles to form in the Duraoat.
