I Dura Coated my Bell &Carlson about a year ago.The most improtant thing with Dura Coat, don't cut corners when your prepping what ever project you are doing. I also did an AR15 in the Winter Twig format the base color is white. I won't do another gun in white , it shows every little smudge of dirt you have on your hands or gloves. I blast all of my projects using aluminum oxide, and i have yet to have any failures. I have done over 30 firearms for people with on complaints.
