I tired Custom Gun Coatings but the wait was very long. Had all my work done w Phoenix Custom Rifles and couldn't be more pleased. They take their time and do it right.
There is a list of Cerakote appliers on the Cerakote website. I believe that at a minimum, you must attend the on premises Cerakote certified training to have your (company) name listed on the Cerakote site. You should check that out, shipping costs from/to Alaska would be ugly.
