I washed the parts with blue Dawn, rinsed and let them dry thoroughly and then wiped with denatured alcohol and a dry cloth. You have to wear rubber gloves when applying the Cerakote. Also, you need to work fairly quickly because it starts to dry after awhile. The most important thing is make sure there's no water present or it will be splotchy.Looks great! What is the process like for applying the Cerakote.
